If you were trying to get to Twitter, ChatGPT, Salesforce, or any number of other sites and you were having issues, it wasn’t you. Cloudflare, who are a content delivery network that also provides network and security products to companies took a dive. If you have a look at their status page, they acknowledge that they had an issue, but it is in the process of being resolved. But as I type this, there are still scattered reports of issues. Chances are, these issues will likely go away as the day goes on.
The folks at Cisco ThousandEyes have an outage map. I also got this statement from them regarding what they observed:
On November 18, 2025, at approximately 11:30 UTC, Cisco ThousandEyes began observing a global outage affecting cloud and CDN provider Cloudflare, impacting multiple Internet services including X, OpenAI, and Anthropic. While network paths to Cloudflare’s front-end infrastructure appeared clear of any elevated latency or packet loss, Cisco ThousandEyes observed a number of timeouts and HTTP 5XX server errors, which is indicative of a backend services issue. While Cloudflare has confirmed they are implementing remediation, the outage is still ongoing. Sample service impacted by the outage: https://cs.co/604475xqg
Thus for those who were hoping for a digital snow day, sorry.
