Investigating
Cloudflare is investigating an issue affecting Cloudflare Gateway DNS-over-TLS (DoT) connections over IPv4. Affected customers may experience connection timeouts and failed DNS resolution. This issue is limited to DoT over IPv4. DoT over IPv6, DNS-over-HTTPS (DoH), and standard DNS over UDP/TCP are not affected. We are working to identify the cause and restore connectivity. Further updates will be provided as more information becomes available.

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.
