All deployments "unexpected_failure" - Production down for 20+ hours

My Vercel project has been completely blocked for over 20 hours. Every deployment fails with the same error at the patchBuild stage:

An unexpected error occurred when running this build. This may be a transient issue, please try rebuilding your project.
What I’ve tried:

  • CLI deploy, GitHub Actions deploy, manual deploy from dashboard
  • Different regions (iad1, sfo1)
  • CDN cache purge
  • Multiple different commits (including one that was previously deployed successfully)
  • Waiting several hours

The pattern:

  • Build completes successfully every time
  • Deployment fails immediately at patchBuild step
  • 10+ consecutive failures across all deployment methods
  • Last successful deployment was May 8th around 08:22 UTC

Vercel support confirmed this is a platform-side issue, but I can’t submit a ticket on Hobby plan. Anyone else experiencing this or know a workaround?

Thanks
