Investigating
Changes to Cloudflare Workers are temporarily not producing Event Subscription events. We have intentionally disabled this feature due to an on-going issue. We are actively working to restore it, but this, regrettably, may take a while. Changes to Workers themselves are working normally. Already deployed Workers are entirely unaffected.

What our checkpoints saw
HostTracker's checkpoints, which test cloudflare.com from several locations, recorded no outage of 5 minutes or longer during this incident. A provider can report a problem that affects only some features, regions or accounts, which a check of the main address does not see. The live Cloudflare status shows what our checks see right now.
Does your product depend on Cloudflare?
An outage like this one reaches your users through your product, and most teams hear about it from a customer rather than from a dashboard. HostTracker watches any endpoint you name - your own site, an API you call, a vendor you resell - from 300+ locations, confirms a failure from several of them before it says anything, and then tells you by email, SMS, voice call or your chat tool.
You get the same record you are reading here for your own services: every outage timestamped, with the checks that observed it.
