We barely had time to recover from the massive outage on November 18, and on December 5, 2025, Cloudflare decided to remind us once again just how dependent the internet is on its services. Although the scale of the incident was smaller this time, users around the world still felt the hiccups in the infrastructure.
The list of victims reads like a "Who's Who" of the digital world. Availability issues, login problems, or "500 Internal Server Error" messages were reported by users of giants such as:
Cloudflare officially labeled the incident as a "minor outage" affecting the dashboard and selected integrations. The glitch was fixed within a few hours, and system statuses returned to normal. So, if something is still not working for you, this time it's probably your provider's fault, not a global router conspiracy.
The most interesting aspect of these outages is the behavior of Downdetector. That's where we all run to check if "it's just me." However, with such large-scale problems, even this service can struggle under the load.
And here we enter a "meta" level that sounds like a joke but isn't. If you've ever wondered, "But what if Downdetector goes down?", the answer is ready. There is actually a DowndetectorDowndetector. Yes, you read that right. It is a fully functional site that checks if the site for checking outages is having an outage.
We live in times when the internet needs monitoring for the monitoring. We are now waiting for DowndetectorDowndetectorDowndetector, because in 2025, anything is possible.
