ok, I know why you see this now


3 months ago

wait what


3 months ago

Oh I see, the origin/railway proxies (on the 66.33.22.0/24 prefix) were just deployed


3 months ago

How aggressively are you monitoring those? Do you keep the connection open?


3 months ago

I don't think so, minutely checks


3 months ago

I'm trying to access the failing URLs from my browser, I get hit with a conn refused (or alike, browser autorefreshes) and afterwards it seems to work fine


3 months ago

could you send me the failing URL in here/over DMs? (does it resolve to an address within 66.33.22.0/24)?


3 months ago

I'll send you the ones my monitors are annoying me about, do want to note that it's intermittent so far

Hi @pg, could you let me know which domains you are experiencing that on?

do you know if its the 66.33.22 IPs or 69.46.46 IPs you're seeing timeouts on?

just got 5 minutes timeout then it fixed itself


3 months ago

Let me know if you see anything else.


3 months ago

Was this from a monitor out of interest? Is the monitor hitting the "ams1" POP? https:///.railway/cdn-trace

Yeah, it was a monitor hitting my own API. The entire app was running into a Cloudflare timeout error, but the Railway metrics were still showing everything as healthy and operating normally so idk what was that

Could you run a traceroute/mtr to that IP from the monitor's network/server if possible? 🙏


3 months ago

not consistent latency... mtr just shows ams eq6 right now, but ill keep retrying


3 months ago

some cloudflare proxied requests are timing out completely


3 months ago

I'd like to see the hops you take before eq6

No timeouts on https://utilities-us-east.up.railway.app/raw right - just via Cloudflare?


3 months ago

timeouts only observed via cloudflare so far


3 months ago

latency spikes on non-cloudflare still a thing but my monitors havent tripped on them


3 months ago

cf-ray became lhr, then timed out the following refresh

(and once again I am able to fetch it fine..)

I'm assuming you disabled the ams pop

I have a suspicion on what it could be. I'm going to disable something and we can see if that resolves it.

Is your domain also proxied by Cloudflare?

Domain management is on CF, but this particular domain is not proxied.

What latency is that tracking? ICMP or HTTP?

This is starting to affect other deployments.

The problem is becoming widespread.

Hey. 

Same here.

Using a VPN, we tested a few other edges.

In a nutshell, railway/europe-west4-drams3a is definitely troubles for us. us-west2 works fine as far as we can tell.


3 months ago

Monitors tripped over *.up.railway.app timeout


3 months ago

so it's no longer necessarily CF specific

I'm also seeing latency spikes from Singapore

(Singapore Railway service -> EU-W Railway service over pubnet)


3 months ago

I'm guessing something was changed about 18 minutes ago? Latency seems better

I’m having the same issue on my Railway-hosted Node/NestJS backend, but Railway support has not responded yet


3 months ago

There's still few latency spikes going on, but not often


3 months ago

Interesting. All of those domains have pointed to the old edge/66.33.22.0/24 for about 8 hours.
