Hey there! We've found the following might help you get unblocked faster:

• 🧵 Load balancing over the private network

• 🧵 Unable to Access Internal Utility Services from NGINX Proxy on Railway

If you find the answer from one of these, please let us know by solving the thread!

Hey, according to the Railway documentation, the multi-region routing is only for public networking. I assume that the private networking's routing is unspecified for multi-region, in which it falls back to the base case of distributing traffic randomly as if the target was a single region service with multiple replicas. I'll ask internally to see if this is the intended behavior.

Yes, thank you. Please check with the Railway team. It’s surprising that Railway can’t route traffic within the same region. With multiple services, this becomes problematic, public requests are routed correctly, but internal traffic is still slow, which makes the setup much less useful.

I found the documentation about the private network, but it doesn’t mention this limitation.

Hey, unfortunately, there is no region awareness when using private networking. I will change the topic of this thread to a feedback for region aware private networking for this feature to be considered.

Yes, I think this is a significant downside for anyone using a microservices architecture. For now, I will try to keep all of my services in the Singapore region only. But I really hope the team will add this feature soon. Thank you for your support.
