Between May 1, 11:01 am – May 1, 11:09 am UTC, users may have seen increased function invocation errors for traffic originated near the ICN1 Vercel CDN region. Requests to static assets/cached content were unaffected this time. We have reverted the change that caused the issue to mitigate this.
We have identified an issue resulting in delayed and/or missing usage data for observability events between 9:00 - 10:30 UTC and 16:50 - 19:30 UTC.
The issue has been identified and resolved. Usage data for observability events for the affected time buckets have been recovered. The affected windows will continue to show missing data - the recovered data will show up as additional usage at recovery timestamps. The total usage count for the period is accurate and no additional actions are required for customers at this time.
