Summary My custom domain jungetools-vis.me (Hobby plan, service jjjmd93y.up.railway.app) is unreachable from mainland China. DNS resolves correctly, but the assigned edge IP 69.46.46.120 appears to be null-routed/blocked by the GFW at the network layer. Could you please rotate/reassign the edge IP for this domain to a different address in your range?

What's happening

The domain resolves consistently to 69.46.46.120 (verified via 8.8.8.8, AliDNS 223.5.5.5, DNSPod 119.29.29.29 — all identical, so this is not a DNS pollution issue).

From mainland China, TCP connections to 69.46.46.120:443 and :80 time out at the handshake (curl hangs at Trying 69.46.46.120:443... and fails with connect timeout). Port 80 fails the same way.

Access works fine through any proxy that exits outside China.

Proof it's the specific IP, not my app or config I forced my own domain to resolve to a different Railway edge IP while keeping the correct SNI, and it returned HTTP 200 immediately:

Blocked IP (the one my domain is pinned to):

curl -v --resolve jungetools-vis.me:443:69.46.46.120 https://jungetools-vis.me

→ Trying 69.46.46.120:443... (connect timeout, fails)

A different Railway edge IP (same SNI/domain):

curl -v --resolve jungetools-vis.me:443:69.46.46.53 https://jungetools-vis.me

→ HTTP/2 200 OK (works perfectly)

So my app, TLS certificate, and domain configuration are all healthy. The only problem is that 69.46.46.120 is being dropped by China's network filtering, while other IPs in your 69.46.46.0/24 range (e.g. 69.46.46.53) are currently reachable from China.

Test environment

Vantage point: Tencent Cloud, Beijing, China (AS45090).

IP owner confirmed via ip-api: 69.46.46.120 → "Railway" (AS400940, Seattle).

Request

Could you rotate/reassign the edge IP for jungetools-vis.me to a different address in your pool (ideally one currently reachable from mainland China)?

If IP selection isn't possible on Hobby, is there any recommended approach for users with a China audience (e.g., a supported CDN/proxy in front)?

I understand Hobby does not guarantee a specific IP — I'm simply asking for a reassignment away from an IP that is currently GFW-blocked. Thank you!
