Between 16:10 and 16:43 UTC on May 22, some customers using Next.js above 16.2.0-canary.28 with Preview Comments enabled experienced build failures during deployments. The issue has been mitigated and follow-up deployments should no longer encounter this error.
Between 1:30 to 3:44 UTC, messages in Vercel Queues in iad1 were enqueued but not processed, and Vercel Workflows were blocked from making progress (i.e. remaining in pending / active states). This is recovering, Vercel Queues backlogs are being processed, and Vercel Workflows are unblocked.
