Cloudflare’s global network suffered a major disruption on Tuesday, November 18, causing widespread instability across multiple online services and triggering a chain reaction of outages reported by users around the world.
The incident began at 11:48 UTC, when Cloudflare disclosed it was investigating an internal service degradation affecting several systems.
By 12:03 UTC, the company acknowledged that users might experience intermittent failures as teams worked to restore service.
Over the next hour, Cloudflare continued to update customers, noting at 12:21 UTC that some functions appeared to be recovering even as error rates remained abnormally high.
At 13:04 UTC, Cloudflare temporarily disabled WARP access in London after connectivity through the secure tunnel began failing.
A fix was identified minutes later, and by 13:13 UTC, Cloudflare announced that both Access and WARP had recovered, with error levels returning to normal.
WARP access in London was subsequently re-enabled. Despite this progress, Cloudflare said as of 13:35 UTC that work remained underway to stabilize other application services.
External monitoring reflected the scale of the outage. Downdetector data showed a sharp rise in Cloudflare-related reports throughout the evening, including 535 reports recorded at 9:41 PM, compared to a baseline that earlier in the day sat at nearly zero. The sudden spike illustrated how quickly the disruption escalated for users.
The incident also affected several major online platforms that rely on Cloudflare’s infrastructure. X (Twitter), Canva, Valorant, League of Legends, and OpenAI all showed simultaneous surges in problem reports, with graphs displaying the same sharp upward jump during the Cloudflare outage window.
The clustering of these reports indicated that users across different apps and services were experiencing failures at the same time, suggesting a broader connectivity impact stemming from Cloudflare’s instability.
Cloudflare separately confirmed an issue with its third-party support portal provider, which caused errors when customers attempted to view or respond to support tickets.
The company emphasized that customer inquiries continued to be received and that Business and Enterprise users could still reach support via live chat or through the emergency hotline. Cloudflare said it is coordinating with the provider to restore full portal functionality.
