Any network traffic (such as sending API requests and receiving responses) counts as egress/ingress (respectively).

Thanks - is there a way to see what the incoming traffic (presumably responses from Resend?) is? - it seems a lot of data to me.

Also - am I correct in thinking that traffic to and from the associated Postgres instance using internal networking would not be included in the 'public networking' chart?

Is there a way to see what the traffic is? Monitoring my local development setup doesn't reveal anything that looks like it would cause MBs worth of ingress.

(sorry for duplicate - do I need to directly respond to replies in here?)

Correct. That would be private networking

Is there a way to see what the traffic is?

Maybe try looking at the HTTP logs per https://docs.railway.com/guides/logs#http-logs

This service doesn't show an HTTP Logs section on the dashboard.

On my local setup I ran a net flow (nfcapd/nfdump) analysis and the amount of traffic with the resend API is measured in kb, what there was a lot of was traffic to/from Postgres as the worker polls the database for tasks. I reduced the polling frequency and the amount of ingress traffic has dropped significantly since which to me suggests that database traffic is being included on the public network ingress even though I'm pretty sure it should all count as 'private' traffic and as far as I can see only private networking is active on my Postgres instance.

I think this is the likely culprit. To set expectations, although this is an annoying bug, I don't have an ETA nor eyes on when we can pick up a remediation on this issue (unless it affects billing, but I don't think this is the case).

Hello!

We're acknowledging your issue and attaching a ticket to this thread.

We don't have an ETA for it, but, our engineering team will take a look and you will be updated as we update the ticket.

Please reply to this thread if you have any questions!

Added a ticket so we can look into the issue and try to re-pro the bug.

Thanks for looking - it's not affecting billing as far as I can tell - I just wasn't sure what I was seeing.

Noted, you should see the Linear bot populate as we get motion on this issue. (Appreciate you raising it up!)
