I use [1.1.1.1](https://en.wikipedia.org/wiki/1.1.1.1) as a DNS server a lot, both personally and professionally. Besides working well, it has some additional advantages, including privacy. Cloudflare, who operates 1.1.1.1, did a great blog post of what happened recently, in the [July 14th incident](https://blog.cloudflare.com/cloudflare-1-1-1-1-incident-on-july-14-2025/).

Given that I depend a lot on it, I also monitor it. Since I use the Ping Every Second extension for it, I have a great view of what happened that day.

First, availability: connectivity disappeared for me at 22:54:29 (all times are Portuguese time: UTC+1) and was back partially at 23:20:41. It wasn’t until 23:42 that it totally recovered:

But I also measure RTT every second.&nbsp;RTT also fluctuated immediately before and after the total connectivity loss was observed, but I was expecting it to be higher than it was, especially with the max values after connectivity returned:

It is very satisfying that what I observed and what Cloudflare detailed in their Incident Timeline is almost a perfect match. But even more impressive is that I was able to get the details at a one second resolution with Dynatrace, and so have a perfect idea of what happened!
