Hi all,

My project deployed successfully on Aug 27 and has been active since.
Today I pushed a very small change (just a couple of variables) and tried to deploy, but I now get “Deployment failed during build process.”

To rule out a code issue, I re-deployed the exact Aug 27 commit (which previously built and ran fine) and it fails with the same error.

Environment

• Region: asia-southeast1

• Build system: Nixpacks v1.38.0

• Base image seen in logs: ghcr.io/railwayapp/nixpacks:ubuntu-1745885067

What the logs show
The failure happens early in the setup when Nixpacks runs apt-get update / apt-get install for system packages. I see repeated timeouts to Ubuntu mirrors, e.g.:

Err:1 http://security.ubuntu.com/ubuntu noble-security InRelease
  Cannot initiate the connection ... (Network is unreachable)
  Could not connect to security.ubuntu.com:80 (...) connection timed out
W: Some index files failed to download. They have been ignored, or old ones used instead.

I haven’t changed anything related to the base image or system packages; this step used to work.

Questions

1. Is there a current platform or network issue affecting builders (e.g., egress to Ubuntu mirrors / IPv6 routing / mirror reachability) in asia-southeast1?

2. Did anything change recently in Nixpacks or the default base image that requires action on my side?

Happy to share deployment IDs and full logs if needed.
Thanks!
