Critical Cloudflare 503's on Express Backend
Two quick questions on outages I've using Cloudflare + Railway
1. Does railway do any rate-limiting? If so, can this be disabled?
2. Is there a more lengthy post about issues when enabling cloudflare for backend services? (beyond what is mentioned here https://docs.railway.app/deploy/exposing-your-app)
What we're seeing is that immediately after enabling the Cloudflare orange cloud, the express backend chokes on 100% of requests returning 503 errors. I've had many back-and-forths with the Cloudflare team and the current guess is that the origin server (Railway) is throwing these 503s.
