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
