Telemetry data loss for Drains

Incident Report for Vercel

Resolved

Between 19:12 and 19:18 UTC on July 23, 2026, telemetry forwarded through Log Drains was not delivered. Logs, traces, and events emitted via drains during this window were dropped and are unrecoverable.

Customers with one or more Log Drains configured on their Vercel projects lost telemetry emitted during the affected window. Data emitted outside the 19:12 and 19:18 UTC window was not dropped.

We have deployed a fix and adding additional monitoring to detect and prevent this failure mode from happening in the future.

We know how much you rely on this data, and we sincerely apologize for the disruption.
