What our checkpoints saw

HostTracker's checkpoints, which test claude.ai from several locations, recorded no outage of 5 minutes or longer during this incident.

Does your product depend on Claude?

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.
