Thanks, can you also specify what you mean that your hostname changed?

sorry that specific language "hostname changed" was the output of an llm in determining what happened. I didn't mean to imply that did happen, just that the llm thought that's what happened.
The curl is directly to my service bypassing cloudflare.

Great, I'll let the team take a quick look as it's awfully close to an incident. Could you double-check that your service has that exact domain attached to it and that it has an active deployment?

how would I check? I use a custom domain but the cloudflare dns points to what I provided. It worked immediately before the incident, that's what I'm going off of. How would I confirm that that was the domain you gave me to map my cname entry to?


18 days ago

Oh, what you shared is a CNAME pointing? That won't work. You have to use your domain instead of that. Railway detects your service by your domain and not CNAME.

Do you get any sort of logs on http logs when trying to reach it via Cloudflare?

On my end

Seeing ~15s response times on all requests to my deployment, including endpoints that do zero I/O (auth rejection returns 401 but takes 15s). This started ~75 minutes ago per Sentry.

Health endpoint returning 502 through Cloudflare due to timeout, also ~15s when hit directly.

Single uvicorn worker, no recent deploys. Suspect this is related to the current platform incident even though it's listed as builds-only.
