Current versus Expected behavior
After enabling the new Static IPs Add-on, all my production deploys started failing with the same error message:
An unexpected error happened when running this build. We have been notified of the problem.
This may be a transient error. If the problem persists, please contact Vercel Support.
Before enabling Static IPs, everything deployed fine.
Now, every build fails around 2 minutes and 30 seconds in with no other log detail.
If I disable Static IPs, deploys succeed immediately again.
This has been happening for about 10 hours.
I have already submitted a support ticket as well #810710
Code, configuration, and steps that reproduce this issue
- Enabled Static IPs Add-on for my project
- Pushed a small commit to trigger a redeploy
- Build failed with the “unexpected error” message
- Tried redeploying the same commit → failed again
- Tried multiple commits (even ones that previously succeeded) → all failed
- Disabled Static IPs → build succeeded immediately
- Re-enabled Static IPs → failure reproduced instantly
Project information
- Framework: Vite
- Environment: Production (main branch and new feature preview branch)
- Last known good commit:
d2af4b8 - First failed commit:
7e73420 - Time between first failure and now: ~10 hours
- Static IPs Add-on: Enabled → fails, Disabled → succeeds

Additional notes
- The first failed commit only changed a Markdown file — nothing affecting build logic.
- Local build completes in ~12 seconds successfully.
- All remote builds fail at roughly the same time (~2m30s) with identical logs.
- Turning off Static IPs resolves the issue immediately.
Hypothesis
This appears to be related to the Static IPs Add-on initialization or routing.
Possibly a propagation delay or infrastructure routing issue when the add-on is first enabled.
Summary
Builds succeed without Static IPs
Builds fail with Static IPs enabled
Reproducible 100% of the time
Ongoing for ~10 hours, and tried multiple times periodically throughout the day.
Likely infrastructure-side issue related to the Static IPs Add-on
Looking to confirm:
- Whether Static IPs require propagation time before first deploy
- If there’s a known temporary build issue tied to this add-on
- Or if any configuration adjustments are needed on my side
Thanks in advance for any insights
