Buggy deployment since migration to EU West | Railway | Page 1

Hello,

I just migrated our backend service (Django) + pg database to EU West.
The service is up, but:

it's slow compared to the staging service (that is hosted on US servers). The service is correctly setup and is using the private database address.
there is no deploy logs (cf screenshot)

Thanks for the help

Any hint? Or should we move back our production to US servers? We won't be able to handle tomorrow load with those latencies.

#

have you tried a simple redeploy?

dry rock Feb 28, 2024, 11:22 PM

#

Yes, restart/redeploy/re-build image, does not work, I don't even see the echo from my docker entrypoint

#

are you also getting no logs from postgres?

dry rock Feb 28, 2024, 11:23 PM

#

I do get logs from postgres

solar turret Feb 28, 2024, 11:23 PM

#

is postgres itself slow?

dry rock Feb 28, 2024, 11:25 PM

#

No, seems ok

solar turret Feb 28, 2024, 11:26 PM

#

okay and can you define slow in this case?

dry rock Feb 28, 2024, 11:27 PM

#

https://heatpump-backend-production.up.railway.app/ping/ sometimes takes 40ms of runtime (X-Runtime header) sometimes 200ms. It does nothing but a query to the db. And other endpoints behave similarly

solar turret Feb 28, 2024, 11:32 PM

#

and what are those numbers when in us?

dry rock Feb 28, 2024, 11:32 PM

#

https://heatpump-backend-staging.up.railway.app/ping/ 30 to 40ms

#

(staging is hosted on US)

#

I'll try to get back to US for now

#

are you located in EU?

dry rock Feb 28, 2024, 11:41 PM

#

yes, created the service when EU servers were not available and we were trying to migrate to reduce latency

solar turret Feb 28, 2024, 11:42 PM

#

is your service back in US now?

dry rock Feb 28, 2024, 11:42 PM

#

Being migrated, there's a volume attached, so it's taking a bit

#

Back in Oregon, logs are working fine again and steady 30ms runtime on /ping.

#

can you try to deploy a minimal reproducible example to EU?

dry rock Feb 29, 2024, 12:04 AM

#

Will do before attempting to migrate again, but another day, it's getting late here.
Thanks for the help !
