Migration to the cloud<\/h2>\n<p><strong>We\u2019re moving from dedicated servers to a &#8220;multiple cloud provider&#8221; setup.<\/strong><\/p>\n<p>This decision wasn\u2019t taken lightly. While some may note concerns about loss of control, our previous provider just didn&#8217;t meet our super-high expectations of reliability and stability, plus it was a limiting factor in other aspects too.<\/p>\n<p>By distributing our infrastructure across trusted cloud providers, we\u2019re ensuring smoother, faster operations and greater resiliency. We know stability is key for you, and this change sets the foundation for it.<\/p>\n<p>With this move, we\u2019ll also have a greater flexibility to scale, and be able to offer more advanced features like multi-location monitoring more easily.<\/p>\n<h2>2. Improved IP resolution cache<\/h2>\n<p>We\u2019ve optimized our DNS IP resolution process, so it now follows DNS TTL more closely. This means faster, more accurate monitoring and real-time responsiveness\u2014improving the overall accuracy of the service.<\/p>\n<h2>3. We recommend to ensure IPv6 is working on your end<\/h2>\n<p><span style=\"font-weight: 400;\">The <a href=\"https:\/\/www.google.com\/intl\/en\/ipv6\/statistics.html\">Internet is steadily moving toward IPv6<\/a>, and so are we! Our new architecture will work with IPv4 for now <strong>but might start to prioritize IPv6 in the near future<\/strong>.<\/span><\/p>\n<p>We understand IPv6 might not be a top priority for everyone right now. Adoption has been quite slow, and many setups still prioritize IPv4. However, we\u2019re positioning ourselves for the future, <strong>which is why we recommend checking that IPv6 works on your end!<\/strong><\/p>\n<p>If your provider doesn&#8217;t support IPv6 yet, don\u2019t worry\u2014you still have time, and IPv4 will continue to work for now.<\/p>\n<h2>4. New IP Addresses (We know, it&#8217;s a pain!)<\/h2>\n<p>Yes, we\u2019re introducing <span style=\"font-weight: 400;\"><a href=\"https:\/\/uptimerobot.com\/help\/locations\/\">new IP addresses<\/a><\/span> as part of this upgrade \u2639\ufe0f<\/p>\n<p>We get it\u2014updating firewall rules can be a hassle. But rest assured, these IPs won\u2019t be changing again anytime soon. Please ensure these new IPs are added to your allowlist to keep your monitoring running smoothly.<\/p>\n<blockquote><p><span style=\"font-weight: 400;\"><strong>Action Required: Please update your firewall rules accordingly and ensure the <a href=\"https:\/\/uptimerobot.com\/help\/locations\/\">IP addresses<\/a> are added to your allowlist<\/strong>.\u00a0<\/span><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">If you run into any issues related to these changes, please don&#8217;t be afraid to reach out to our support team.<\/span><\/p>\n<h2>What&#8217;s in for you?<\/h2>\n<p>We\u2019re laying the groundwork for several new features we\u2019ve been developing based on <a href=\"https:\/\/uptimerobot.nolt.io\/\">your valuable feedback<\/a>. The updated infrastructure will enable multi-location monitoring, and we\u2019re also excited about response time monitoring, both of which are coming soon \ud83d\udc40<\/p>\n<p>These improvements will bring tangible benefits that improve the quality and scope of the services you rely on. We know there\u2019s more to discuss, and we\u2019d love to hear your thoughts in the comments.
