It delivers three core benefits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Continuous web access: <\/strong>DNS is the very first step in connecting to any web service. If it fails, your entire website or application becomes unreachable, even if hosting, databases, and applications are running fine. It\u2019s like having a store open for business but with no address in the GPS. Customers simply can\u2019t find you.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Better performance and SEO: <\/strong>Slow DNS resolution adds delays to every user request. That frustrates visitors, increases bounce rates, and can even harm your search engine rankings.

Now, let\u2019s talk about the key metrics you should track to monitor the performance and health of your DNS servers effectively.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image5-2.webp\" alt=\"Key metrics to monitor for effective DNS performance and security\" class=\"wp-image-539\" srcset=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image5-2.webp 1024w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image5-2-300x225.webp 300w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image5-2-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Key metrics to monitor for effective DNS performance and security<\/figcaption><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\">Query resolution time (latency)<\/h3>\n\n\n\n<p>Query resolution time measures how long it takes for a DNS server to translate a domain name (like <a href=\"http:\/\/example.com\">example.com<\/a>) into its corresponding IP address.&nbsp;<\/p>\n\n\n\n<p>High latency can result in a slow user experience and also impact your site\u2019s search engine rankings. Monitoring this helps you spot delays before they affect visitors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DNS record propagation time<\/h3>\n\n\n\n<p>When you update DNS records, those changes don\u2019t take effect instantly. Propagation time measures how long it takes for updates to be reflected across all DNS servers worldwide.&nbsp;<\/p>\n\n\n\n<p>If propagation is slow, users may be directed to outdated servers or experience downtime until the changes fully spread.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">NXDOMAIN\/SERVFAIL error rates<\/h3>\n\n\n\n<p><strong>NXDOMAIN<\/strong> errors occur when a requested domain name does not exist.<\/p>\n\n\n\n<p><strong>SERVFAIL<\/strong> errors indicate that the DNS server was unable to process a query.&nbsp;<\/p>\n\n\n\n<p>Spikes in these error rates often point to misconfigurations, server outages, or even active attacks such as DNS spoofing or DDoS. Monitoring these metrics helps you detect problems early and troubleshoot them before they escalate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">SOA serial number changes<\/h3>\n\n\n\n<p>The Start of Authority (SOA) record contains a serial number that increases each time the DNS zone file is updated. Monitoring this number ensures that updates are being applied correctly and consistently.&nbsp;<\/p>\n\n\n\n<p>Unexpected or unauthorized changes can signal misconfigurations or even malicious tampering, making this a critical metric for maintaining DNS integrity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">TTL (time-to-live) expiration<\/h3>\n\n\n\n<p>The TTL value defines how long DNS records are cached by resolvers before fresh data must be requested. Short TTLs allow changes to propagate quickly but increase server load, while long TTLs reduce load but delay updates.&nbsp;<\/p>\n\n\n\n<p>Monitoring TTL settings helps strike the right balance between fast updates and efficient DNS performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Unusual spikes in DNS requests<\/h3>\n\n\n\n<p>Sudden surges in DNS query traffic can be a warning sign, especially if they originate from unexpected regions or unfamiliar IP addresses. Such spikes may indicate DDoS or DNS amplification attacks, or misconfigured clients repeatedly querying your servers.&nbsp;<\/p>\n\n\n\n<p>Watching these unusual traffic patterns helps detect threats early and protects your infrastructure from overload and abuse.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Record changes (A, AAAA, MX, TXT, NS)<\/h3>\n\n\n\n<p><a href=\"https:\/\/uptimerobot.com\/knowledge-hub\/devops\/dns-record-types-explained\/?utm_source=Uptimerobot&amp;utm_medium=blog&amp;utm_campaign=DNS%20monitoring&amp;utm_content=key%20metrics\" target=\"_blank\" rel=\"noreferrer noopener\">DNS records<\/a>, such as A, AAAA, MX, TXT, and NS, control essential functions like domain routing, email delivery, verification, and delegation. Monitoring changes to these records helps ensure that unauthorized or accidental modifications don\u2019t occur.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of DNS monitoring<\/h2>\n\n\n\n<p>Let\u2019s explore the different types of DNS monitoring and how each plays a unique role in keeping your DNS healthy and secure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Synthetic monitoring<\/h3>\n\n\n\n<p><a href=\"https:\/\/uptimerobot.com\/knowledge-hub\/monitoring\/what-is-synthetic-monitoring\/?utm_source=Uptimerobot&amp;utm_medium=blog&amp;utm_campaign=DNS%20monitoring&amp;utm_content=types\" target=\"_blank\" rel=\"noreferrer noopener\">Synthetic monitoring<\/a>, also known as directed monitoring, involves creating artificial DNS queries from multiple locations to continuously test DNS performance and availability, even without real user traffic.&nbsp;<\/p>\n\n\n\n<p>Checking response times and resolution success in advance helps identify potential issues before they impact real users.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Real user monitoring (RUM)<\/h3>\n\n\n\n<p>Real User Monitoring (RUM) complements synthetic monitoring by capturing DNS resolution times and errors directly from actual users\u2019 browser sessions.&nbsp;<\/p>\n\n\n\n<p>By analyzing real-world data across devices, networks, and regions, RUM provides insight into how DNS performance impacts user experience. It helps detect localized issues that synthetic monitoring might miss, giving a more complete view of DNS behavior in the wild.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Recursive server monitoring<\/h3>\n\n\n\n<p>Recursive server monitoring tracks the health and performance of internal DNS resolvers, such as those in enterprise networks or Kubernetes clusters.<\/p>\n\n\n\n<p>It ensures these servers correctly handle DNS requests, maintain proper caching, and avoid failures that could disrupt internal services.<\/p>\n\n\n\n<figure class=\"wp-block-table aligncenter\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Feature\/Aspect<\/strong><\/td><td><strong>Synthetic monitoring<\/strong><\/td><td><strong>Real user monitoring<\/strong><\/td><td><strong>Recursive server monitoring<\/strong><\/td><\/tr><tr><td><strong>What it does<\/strong><\/td><td>Simulates DNS queries from test locations globally<\/td><td>Collects DNS data from actual user sessions<\/td><td>Monitors internal DNS resolvers and recursive servers<\/td><\/tr><tr><td><strong>Data source<\/strong><\/td><td>Controlled synthetic tests<\/td><td>Real user browser or device data<\/td><td>Internal DNS servers<\/td><\/tr><tr><td><strong>Purpose<\/strong><\/td><td>Proactive detection of DNS issues<\/td><td>Real-world performance and error insights<\/td><td>Ensuring internal resolver health and accuracy<\/td><\/tr><tr><td><strong>Benefits<\/strong><\/td><td>Early warning, consistent testing environments<\/td><td>Accurate user impact data, location-specific insights<\/td><td>Internal service reliability, cache management<\/td><\/tr><tr><td><strong>Limitations<\/strong><\/td><td>Doesn\u2019t reflect real user behavior<\/td><td>Dependent on sufficient user traffic data<\/td><td>Limited to internal network scope<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Common DNS problems you can detect with monitoring<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"978\" height=\"1024\" src=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2-978x1024.webp\" alt=\"Common DNS problems you can detect with monitoring\" class=\"wp-image-540\" srcset=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2-978x1024.webp 978w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2-286x300.webp 286w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2-768x804.webp 768w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2-1467x1536.webp 1467w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image3-2.webp 1909w\" sizes=\"auto, (max-width: 978px) 100vw, 978px\" \/><figcaption class=\"wp-element-caption\">Common DNS problems you can detect with monitoring<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Let us look at the most common DNS problems you can uncover through monitoring:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DNS record misconfigurations<\/h3>\n\n\n\n<p>DNS record misconfigurations happen when records like A or MX have incorrect IP addresses or settings.&nbsp;<\/p>\n\n\n\n<p>These errors can misroute traffic, causing website downtime, email delivery issues, or other service disruptions. Continuous monitoring helps detect and resolve misconfigurations before they impact users.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Expired records are not being renewed<\/h3>\n\n\n\n<p>DNS records come with expiration dates and must be renewed on time. If they expire, users may be unable to access your domain or services. Monitoring helps track upcoming expirations, sending alerts so you can renew records promptly and avoid downtime.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cache poisoning or hijacks<\/h3>\n\n\n\n<p>Cache poisoning injects false DNS data into a resolver\u2019s cache, redirecting users to malicious sites. DNS hijacking involves unauthorized changes to records. Monitoring unusual queries and unexpected record changes helps detect and stop these attacks early.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">High-latency resolution from specific regions<\/h3>\n\n\n\n<p>DNS queries from certain regions may take longer to resolve due to network issues, misconfigured servers, or geo-blocking.&nbsp;<\/p>\n\n\n\n<p>Monitoring latency by location helps identify these regional performance problems, allowing you to optimize DNS routing or switch providers to improve user experience.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DNSSEC failures or validation issues<\/h3>\n\n\n\n<p>DNS Security Extensions (DNSSEC) safeguard DNS data by digitally signing it to prevent tampering. Failures or validation errors can leave users vulnerable to spoofing or man-in-the-middle attacks. Monitoring DNSSEC ensures that DNS responses remain authentic and trustworthy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Unexpected TTL or SOA serial changes<\/h3>\n\n\n\n<p>TTL (Time-to-Live) determines how long DNS data is cached, and the SOA serial number tracks updates to the DNS zone file. Sudden or unauthorized changes in these values can signal misconfigurations or malicious activity, potentially disrupting DNS functionality. Continuous monitoring helps maintain DNS stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Intermittent failures from specific resolvers<\/h3>\n\n\n\n<p>Occasionally, certain recursive DNS servers or specific regions may experience resolution failures due to localized network issues or server outages. Monitoring these intermittent, isolated failures helps identify and resolve problems before they escalate and impact more users.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">DNS monitoring for security<\/h2>\n\n\n\n<p>DNS monitoring gives you visibility into one of the most common attack targets on the internet. By watching DNS traffic closely, you can pick up on compromise attempts, reduce the risk of data leaks, and maintain trust in your domain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Monitor for unusual query patterns<\/h3>\n\n\n\n<p>Attackers often use DNS tunnels or unusual query types to secretly exfiltrate data or communicate with malware. By monitoring query volume, frequency, and patterns, you can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Set thresholds and alerts<\/strong> for sudden spikes in queries from unusual sources.<\/li>\n\n\n\n<li><strong>Investigate unusual query types<\/strong> that don\u2019t match your normal traffic.<\/li>\n\n\n\n<li><strong>Correlate anomalies with endpoint or network logs<\/strong> to detect potential breaches.<\/li>\n\n\n\n<li><strong>Block suspicious IPs or domains<\/strong> showing abnormal query behavior.<\/li>\n\n\n\n<li><strong>Maintain historical trends<\/strong> to quickly spot deviations from normal traffic patterns.<\/li>\n<\/ul>\n\n\n\n<p>These steps help you respond proactively before attacks impact your infrastructure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Catch DNS hijacking or cache poisoning<\/h3>\n\n\n\n<p>DNS hijacking occurs when attackers make unauthorized changes to DNS records, redirecting users to malicious sites. Cache poisoning corrupts DNS caches with false information. Monitoring allows you to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Receive alerts on unexpected record changes<\/strong> in A, AAAA, MX, TXT, or NS records.<\/li>\n\n\n\n<li><strong>Compare live DNS responses with known-good baselines<\/strong> to spot discrepancies.<\/li>\n\n\n\n<li><strong>Track cache inconsistencies across resolvers<\/strong> to detect poisoned entries.<\/li>\n<\/ul>\n\n\n\n<p>These actions help prevent user redirection, maintain trust, and protect sensitive data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Validate DNSSEC configurations<\/h3>\n\n\n\n<p>DNS Security Extensions (DNSSEC) add cryptographic signatures to DNS records, ensuring that the data received from a DNS query is authentic and hasn\u2019t been tampered with. By actively monitoring and validating DNSSEC configurations, you can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Catch expired keys, broken signatures, or missing DNSSEC records<\/strong> before they compromise security.<\/li>\n\n\n\n<li><strong>Ensure that DNS responses are actually from your authoritative servers<\/strong>, protecting users from being redirected to malicious sites.<\/li>\n\n\n\n<li><strong>Maintain the chain of trust<\/strong> by continuously validating that your DNSKEY records align with the root zone and parent domains, preventing tampering along the DNS path.<\/li>\n\n\n\n<li><strong>Reduce the risk of man-in-the-middle attacks <\/strong>and enhance user trust by validating DNSSEC configurations consistently.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Spot sudden spikes in NXDOMAIN or timeouts<\/h3>\n\n\n\n<p>A sudden spike in <a href=\"https:\/\/uptimerobot.com\/knowledge-hub\/monitoring\/fix-dns-probe-finished-nxdomain-error\/?utm_source=Uptimerobot&amp;utm_medium=blog&amp;utm_campaign=DNS%20monitoring&amp;utm_content=monitoring%20for%20security\" target=\"_blank\" rel=\"noreferrer noopener\">NXDOMAIN<\/a> responses or timeouts indicates attacks, misconfigurations, or server issues.

Use charts and graphs to track metrics like query latency, NXDOMAIN\/SERVFAIL rates, TTL expirations, and SOA serial updates.&nbsp;<\/p>\n\n\n\n<p>Visual dashboards make it easy to spot patterns, catch recurring issues, and make informed decisions to improve DNS performance and security.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to triage a DNS alert fast<\/h2>\n\n\n\n<p>When a DNS alert fires, start by checking the scope. See whether it affects one record, one resolver, one region, or the whole zone. A regional issue often points to caching, propagation, or provider routing. A wider failure usually points to a broken record, nameserver issue, or expired domain setting.<\/p>\n\n\n\n<p>Next, compare the live answer with your expected baseline. Check A and AAAA records, CNAMEs, MX records, NS records, and TXT values against the last known good state. Unexpected changes in NS, MX, or TXT records should move to the front of the queue because they can break mail flow, delegation, or domain verification.<\/p>\n\n\n\n<p>Then separate correctness problems from performance problems. Slow resolution with the right answer usually points to overloaded resolvers, network latency, or weak regional coverage. Wrong answers, NXDOMAIN, SERVFAIL, or timeouts usually point to misconfigurations, propagation problems, DNSSEC issues, or provider outages.<\/p>\n\n\n\n<p>After that, test from more than one location. DNS can look healthy from one network and fail from another because caches and recursive resolvers do not update at the same time. Multi-location checks help you tell the difference between a temporary local issue and a broader problem.<\/p>\n\n\n\n<p>Finish by matching the alert to the right action. Roll back unintended record changes, lower TTL before planned migrations, contact your DNS provider for resolver or nameserver failures, and review access logs if a record changed without approval. Then update your known-good record set, so the next alert is faster to verify and easier to fix.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Best DNS monitoring tools in 2025<\/h2>\n\n\n\n<p>We have established the importance of DNS monitoring, let us now look at the best DNS monitoring tools you can use in 2025.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">UptimeRobot<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"579\" src=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1-1024x579.webp\" alt=\"UptimeRobot\" class=\"wp-image-546\" srcset=\"https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1-1024x579.webp 1024w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1-300x170.webp 300w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1-768x434.webp 768w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1-1536x868.webp 1536w, https:\/\/uptimerobot.com\/knowledge-hub\/wp-content\/uploads\/2025\/08\/image9-1.webp 1992w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">UptimeRobot<\/figcaption><\/figure>\n<\/div>\n\n\n<p><strong>UptimeRobot<\/strong>, one of the most trusted uptime monitoring platforms, has recently expanded its toolkit with <a href=\"https:\/\/uptimerobot.com\/dns-monitoring\/?utm_source=Uptimerobot&amp;utm_medium=blog&amp;utm_campaign=DNS%20monitoring&amp;utm_content=tools\" target=\"_blank\" rel=\"noreferrer noopener\">DNS Monitoring<\/a>.

E-commerce brand improves DNS resolution in Asia<\/h3>\n\n\n\n<p><strong>Problem: <\/strong>An international e-commerce company noticed that customers in Asia were experiencing slower website load times, especially during peak shopping hours. The servers themselves were performing well, but DNS resolution was significantly delayed for users in certain regions.<\/p>\n\n\n\n<p><strong>Solution:<\/strong> By implementing DNS monitoring with synthetic tests from multiple global locations, the team was able to identify the root cause. Their DNS provider had limited points of presence (PoPs) in Asia. Armed with this insight, they switched to a provider with better geographic coverage.<\/p>\n\n\n\n<p><strong>Result:<\/strong> DNS response times improved dramatically, leading to faster page loads, an enhanced user experience, and higher conversion rates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. DevOps engineer prevents weekend outage with SOA alert<\/h3>\n\n\n\n<p><strong>Problem:<\/strong> Ahead of a long weekend, a DevOps engineer received an unexpected alert from the DNS monitoring system: <em>the SOA (Start of Authority) serial number had changed<\/em>. No DNS updates were scheduled, and nothing was logged in the deployment pipeline.<\/p>\n\n\n\n<p><strong>Solution:<\/strong> The alert prompted an immediate investigation, revealing that a staging environment had accidentally pushed a zone file update to production. Because DNS monitoring flagged the discrepancy early, the engineer was able to correct the misconfiguration before it impacted users.<\/p>\n\n\n\n<p><strong>Result:<\/strong> The potential weekend outage was averted, ensuring uninterrupted service during a period of limited support coverage. Early detection prevented widespread resolution failures and reinforced the value of continuous DNS monitoring.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Marketing team prevents campaign disruption with CNAME alert<\/h3>\n\n\n\n<p><strong>Problem:<\/strong> During the launch of a major digital marketing campaign, the marketing team added a new subdomain intended to redirect to a third-party landing page. Unfortunately, the CNAME record was misconfigured, breaking links in paid ads and emails.<\/p>\n\n\n\n<p><strong>Solution:<\/strong> Thanks to DNS monitoring, the missing CNAME record was flagged within minutes of deployment. The DevOps team received the alert and corrected the configuration immediately.<\/p>\n\n\n\n<p><strong>Result:<\/strong> Redirection was restored before most users encountered the issue, saving ad spend and ensuring a smooth campaign rollout.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Security Team stops malicious TXT record injections<\/h3>\n\n\n\n<p><strong>Problem:<\/strong> During a routine DNS check, the security team discovered unauthorized TXT records in the company\u2019s main domain. These suspicious entries weren\u2019t part of any legitimate configuration and could have been used for phishing, spoofing, or malware campaigns.<\/p>\n\n\n\n<p><strong>Solution:<\/strong> The alert prompted an immediate investigation, which uncovered a compromised admin account with DNS modification rights. The team quickly revoked access, removed the malicious records, and audited the DNS change process to prevent future incidents.<\/p>\n\n\n\n<p><strong>Result:<\/strong> Early detection through DNS monitoring prevented a potentially serious security breach, protecting the organization from reputational and operational damage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final thoughts: Make DNS monitoring a priority<\/h2>\n\n\n\n<p>DNS keeps your network running. When it fails, mail servers, web servers, APIs, and customer trust are all at risk. A single misconfigured or compromised record can redirect users, cause outages, or open the door to attacks.<\/p>\n\n\n\n<p>DNS monitoring is essential for keeping your servers reliable and accessible. It continuously tracks records, detects misconfigurations, and alerts you to unexpected changes. This helps prevent downtime, block malicious activity, and maintain a seamless experience for your users.<\/p>\n\n\n\n<p>From global ecommerce platforms to enterprise networks, DNS monitoring gives you visibility and control over one of the most critical layers of your infrastructure. Make it a core part of your operations and resolve issues before they impact your business.<\/p>\n\n\n\n<p>Keep your DNS in check with UptimeRobot, because when DNS stops, everything stops.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-a89b3969 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/dashboard.uptimerobot.com\/sign-up\" target=\"_blank\" rel=\"noreferrer noopener\">Start monitoring free<\/a><\/div>\n<\/div>\n\n\n\n<div id=\"faq\" class=\"faq-block py-8 \">\n            <h2 id=\"faq\" class=\"faq-block__title\">\n            FAQ        <\/h2>\n    \n    <ul class=\"faq-accordion\" data-faq-accordion>\n                    <li class=\"faq-accordion__item\">\n                <button \n                    class=\"faq-accordion__title\"\n                    type=\"button\"\n                    aria-expanded=\"false\"\n                    data-faq-trigger>\n                    <h3 id=\"what-is-dns-monitoring\" class=\"faq-accordion__question\">\n                        What is DNS monitoring?                    <\/h3>\n                    <span class=\"faq-accordion__icon\" aria-hidden=\"true\">+<\/span>\n                <\/button>\n                <div class=\"faq-accordion__content-wrapper\">\n                    <div class=\"faq-accordion__content\">\n                        <div class=\"faq-accordion__content-inner\">\n                            <!-- wp:paragraph -->\n<p>DNS monitoring is the process of regularly checking your domain\u2019s DNS records to ensure they are accurate, responsive, and secure.
