Sudden increase in /v1/responses timeouts on gpt-4.1-mini (stable for months, started recently)

Thanks for the response, Mark. Things do seem to be better now.
You mention this lines up with the recent Responses API outage, but looking at the status page, I see a “Responses API Streaming Error” listed for the 16th, but the 17th, 18th, and 19th, which were the worst days for us, report “No Incidents”.
Is there any more reliable way to determine if this is an outage, in the future?
