## Updates from Vercel
### 2026-07-23 19:00 UTC: resolved
Between 19:12 and 19:18 UTC on July 23, 2026, telemetry forwarded through Drains was not delivered. Traces and events forwarded via Drains during this window were dropped and are unrecoverable. Logs forwarded via Drains during this window were also not delivered, but remain accessible in the Logs UI dashboard, where they can also be exported.
We have deployed a fix and are 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.

From the builder: does your app depend on Vercel? [Sazabi](https://www.sazabi.com/?utm_source=down-guide&utm_medium=markdown&utm_content=vercel) detects problems in your own logs without hand-written monitors, and you can ask it in plain language which errors mention Vercel.
