Charged for pretty much unused app

[greg]

Hmm. From the top-left corner, I assume that was a postgres database (as the app’s name ends “-db”)? If so then there will be a larger than expected data transfer, even if idle, due to the way that works internally (with replication and stolon).

The good news is that Fly are great about that kind of thing:

Outbound data transfer for Postgres

Stolon and replication do a lot of traffic, even on idle DBs. It doesn’t really scale with usage but it’s kind of a scary number. We’re going to turn off billing for postgres data transfer until we can otherwise exclude in region traffic. We’ll have to charge a (reduced) cross region rate at some point, but there’s no reason y’all should have to wait on us to do more networking work to reap those benefits.

They’ll be able to investigate.
