Hi Railway Support,

Our frontend service builds have been consistently failing for the past several hours. Every build attempt gets stuck at the image pull/resolve step and times out after exactly 20 minutes with the error:

Build Failed: build daemon returned an error < failed to run Build function: Canceled: context canceled >

This happens with both Dockerfile and Nixpacks builds. The build is always scheduled on the same Metal builder builder-fsjlwt and always fails at the same stage:

• Dockerfile builds: hangs at [internal] load metadata for docker.io/library/node:18-slim
• Nixpacks builds: hangs at resolve image config for docker-image://ghcr.io/railwayapp/railpack-frontend:v0.17.2

The service was deploying successfully before today. No significant changes were made to our build configuration. It appears that builder-fsjlwt is unable to pull container images from registries.

Project details:

• Service root directory: frontend
• Builder assigned: builder-fsjlwt
• Multiple failed attempts between 11:44 UTC and 13:39 UTC on Feb 25, 2026

Could you please investigate the builder or reassign our builds to a different one?

Thank you.
