Hi Railway team,

I've been experiencing persistent build failures (this is my 5th attempt) due to network connectivity issues in the build environment.

Error: During the Docker build, the add-apt-repository -y ppa:deadsnakes/ppa command fails because Launchpad's API is unreachable:

OSError: [Errno 101] Network is unreachable

The full traceback shows httplib2 failing to establish a socket connection to api.launchpad.net.

Build step failing:

dockerfile

RUN apt-get update && apt-get install -y ... \
  && add-apt-repository -y ppa:deadsnakes/ppa \
  && apt-get update && apt-get install -y python3.11 ...

Details:

• This is not a code change issue - the same Dockerfile worked previously

• The error occurs consistently across multiple rebuild attempts

• The build runner appears to have no outbound network access to Ubuntu/Launchpad services

Could you please investigate whether there's a network issue with the build runners in my region, or if there are any known outages affecting external connectivity during builds?

Thanks, Christophe

(it is happening on my "new-api" env in railway "step_app_railway")
