All deployments fail at patchBuild stage - "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:
*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

**Project:**
- portraitpay (prj_6FYHbjqW3UebcAxGAwuIk0wXcVpr)
- portraitpayai.com is currently serving an old deployment

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?

Hi @hd10011390276 we’re looking into this and releasing a fix shortly! Sorry for the trouble. This would have only affected if you were using edge runtime middleware + experimentalServices beta feature Services

You could also switch to node runtime middleware! Node runtime middleware performs better than edge runtime, this is the most recommended path forward

This should be resolved now

Thank you so much, Shohei!
