Hey @Mark — checkout is throwing 500s. Can you review the production errors from the last hour?

Found it. 47 checkout 500s since 8:52 AM. All of them trace to the payments service — a timeout introduced by last night's deploy. Reads are healthy; only the capture step is failing.

Rollback makes sense. @Mark open an incident and page the payments on-call.

Incident opened — INC-2094, severity 2. I've paged the payments on-call and started a live timeline in #incidents. Rollback is staged and waiting on your go.
