might've been resolved on its own?

will look around


I just had it happen on railway.com as well


I'm in eu ams

affected services whose healthchecks failed externally


Seeing latency spikes

everything seems to be stable the last 30m, but might just be luck

ok, I know why you see this now


15 days ago

wait what


15 days ago

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


15 days ago

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


I don't think so, minutely checks


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


15 days ago

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


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?

seeing timeouts, question mark


14 days ago

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


69.46.46.58


resolved ""itself"" as of now but

just got 5 minutes timeout then it fixed itself

Let me know if you see anything else.

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? 🙏


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


some cloudflare proxied requests are timing out completely


14 days ago

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

What is the x-railway-edge header you see here?


railway/europe-west4-drams3a



same edge val, cf-ray ending in -ams

Ty


timing out for me



and... not anymore


14 days ago

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


timeouts only observed via cloudflare so far


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


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

Nope it's still up, do you see that on the non-CF domain as well?


I do not

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.


still seeing these (or should I just wait a bit more)


14 days ago

What latency is that tracking? ICMP or HTTP?

still going cf ams -> hikari lhr


non-proxied latency spikes still occurring

Is there a specific domain this is occuring on or is it all of your domains?

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.


Monitors tripped over *.up.railway.app timeout


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)


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


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


13 days ago

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