Interestingly, Cloudflare had earlier posted that it was planning “scheduled maintenance” on some of its servers – could this have caused the issue?
“We will be performing scheduled maintenance in SCL (Santiago) datacenter on 2025-11-18 between 12:00 and 15:00 UTC,” the company said on its status page.
“Traffic might be re-routed from this location, hence there is a possibility of a slight increase in latency during this maintenance window for end-users in the affected region. For PNI / CNI customers connecting with us in this location, please make sure you are expecting this traffic to fail over elsewhere during this maintenance window as network interfaces in this datacentre may become temporarily unavailable.”
If you’re not familiar with the company, Cloudflare provides a wide range of online infrastructure backing up some of the world’s biggest websites.
The company’s offerings inlcude protection services against cyberattacks, particularly DDoS attacks, where victims are bombarded with huge numbers of requests.
Cloudflare has confirmed the problem, posting at 11.48am GMT;
“Cloudflare is aware of, and investigating an issue which impacts multiple customers: Widespread 500 errors, Cloudflare Dashboard and API also failing.
“We are working to understand the full impact and mitigate this problem. More updates to follow shortly.”
First off – the issue appears to have hit a number of major websites, including X, formerly known as Twitter, film reviewing site Letterboxd – and even outage tracker website DownDetector, which is making tracking the issue quite tricky for us…
