Compare the same feature and time window across broad regions. Ask whether the reports use the same app version or web route, because different clients can make a regional pattern look stronger than it is.
Record local times with time zones or convert them to UTC. Keep locations broad; exact addresses and account details are unnecessary. A few matching reports suggest a pattern, but an official status update or independent checks are still needed before calling it a service-wide outage.
