Railpack build failing - 503/504 Error fetching mise
Hey all, my build is failing during the setup phase. It looks like the Railpack builder is trying to download mise from GitHub, but failing due to an upstream network issue.
Error logs:
ERR0 failed to ensure mise is installed: failed to download and install: temporary failure fetching https://github.com/jdx/mise/releases/download/v2026.10.14/mise-v2026.10.14-linux-x64-musl.tar.gz: unexpected status 503 Service Unavailable
railpack process exited with an error
Details:
- Build Driver: railpack-v0.4.3.0
- Issue is a temporary network failure (503/504) when reaching out to GitHub.
What I've tried:
- Redeployed 3 times.
- Verified there are no network constraints on my end (Railway is failing to reach GitHub's release servers).

We're sorry for the trouble. GitHub is currently having an outage, and builds that need to download from GitHub are failing. That includes the mise download your Railpack build fetches from GitHub's release servers, which is why it returns a 503. We're monitoring this as the GitHub Outage Affecting Builds incident, and you can follow updates at the incident page.
