340 MB of outbound bandwidth on unused postgres instance

[greg]

There is data transfer due to replication, as well as for the app. May be that:

Outbound data transfer for Postgres

This is a little confusing. “Outbound data transfer” is just transmit data from your VM interfaces. So it does include replication and data between your application and database. We need to do some networking work to account for “internal” vs “external” data, hopefully we get this cleaned up in the next couple of months.

The good news is Fly are great with bandwidth and assuming your database app has no public IP, (and so if you only connect to it privately from other apps) currently Fly won’t bill you for the internal bandwidth used. Might need @kurt to confirm.
