My Spring Boot backend service (stockiq-backend-production.up.railway.app) suddenly became unreachable with DNS resolution failures (net::ERR_NAME_NOT_RESOLVED). The service wasn't deleted or modified on my end - it simply stopped resolving.

I'm on the $20/month paid plan, so this shouldn't be related to usage limits or idle timeouts.

The only fix was to manually trigger a redeploy, after which everything worked again.

Could you please investigate what caused the service to become unreachable? I'd like to understand the root cause to prevent this from happening again in production.
