State the broad region, time window, platform, network type, and where playback stalls. Measure roughly how long it takes to start and whether buffering recurs at the same timestamp. Note whether a lower quality setting changes the result and whether another service streams normally, but do not treat either check as proof of a regional server fault.
Check official incident information and compare independent reports where possible. Keep private URLs and account data out of public posts. A short timeline from start to failure helps responders compare delivery paths. If playback later recovers, include the time and the quality tested.
