Okay i think i see the issue, your service is connecting to the redis database and the sql database via the public network, thus you are subjecting yourself to egress fees

This service has always been using public networks. The data usage has been stable, but yesterday it exceeded more than 10 times the usual amount, which is abnormal.

I think this is a bug in the railway

all your metrics (cpu, mem, net) line up with each other to indicate that there was increased usage of your app, this wouldnt be a bug, your app simply used more of everything during that timespan
