While the world is getting more optimistic with the wave of vaccine options, we’re looking forward to introducing you to our latest news. 

We’re happy to say we managed to fulfill some of our last year’s promises and are still working on our plans and improving UptimeRobot. We introduced a completely redesigned mobile app and new status pages, with many new features. 

We entered the new year enthusiastically and kept on being busy. Let’s take a look at what’s new!

New IP Block

We are constantly expanding the infrastructure as the demand for our services increases. Lately, we have added another block of IPs we will start using for our monitoring engines in a few months.

Nothing will change regarding our current IPs. In case you need to whitelist them, you can always check the up-to-date list of UptimeRobot’s IPs

The new IP block is 208.115.199.XX

Integrations

What you can start looking into already is the new UptimeRobot Plesk integration!

We’ve also partnered with PagerDuty to make our integration more official and more publicly visible on their side as well. Nothing will change in terms of your existing configurations, but we’re exploring the possibilities of closer collaboration.

Improved Heartbeat and SSL Monitoring

The Heartbeat monitor was in public BETA until recently, and even though there still were some small issues after the full release, we managed to improve the reliability and stability. 

We also added support for more SSL errors to widen the use of our SSL monitoring and improved the reliability as well. 

Mobile App Updates

We’re really happy you like our new mobile app for iOS and Android. The 4.5-star rating in Google Play and 4.7 in the App Store are proving it.

As promised, we are adding localization support for Spanish, German, French and Portuguese. We’ll consider adding more languages based on the needs of our community. 

We also added notification on auto-signout and improved the stability and performance. 

APIv2 Updates

Last but not least, we made some updates last month regarding our API (CORS Headers, etc.). In case you missed it you can read about it in more detail in the dedicated blog post

What’s next? 

We’d like to keep on posting monthly updates and news, so fingers crossed! There’s still a lot on our plate this year, including sub-accounts, email reports, root causes and custom HTTP(S) timeouts

See you all in a month!

Regarding the list of IP addresses, I think you should update or delete the old https://uptimerobot.com/inc/files/ips/IPv4.txt file, which my systems have been monitoring for changes.

I guess I'll switch to monitoring https://uptimerobot.com/inc/files/ips/IPv4andIPv6.txt instead.

Hi Peter, thank you for bringing this to our attention, yes please switch to the new file.

Would love to see security key support for 2FA, and multiple account support for the Android app. Are you actively working on those?

Kristian - Community Manager Author Mar 17, 2021 at 8:10 am

Hi there! 2FA is available from the Web App, just log in to your Dashboard at UptimeRobot.com and you should find it there under "My Settings". Multiple account support is planned, but there are no details regarding it available yet.

hi none of my monitors work to monitor https best buy store url.

they all been down all the time

Kristian - Community Manager Author Apr 27, 2021 at 2:55 pm

Hi, yes, unfortunately, we can't affect if someone decides to block our requests like BestBuy did. We tried to reach out to them but no luck yet.

I was hoping there was an option for using the Heartbeat Monitor as part of the free service. I just have one location to monitor and a heartbeat every 15 minutes would be more than adequate for my needs.

Kristian - Community Manager Author May 13, 2021 at 2:27 am

Hi Dean, thank you for reaching out to us, the Heartbeat monitor is available for PRO plan only, unfortunately.
