FRA edge issue?

Hello everyone, recently I have been observing response time issues with my VMs in the FRA region (we are located in a single region). The Supabase database is also in the FRA region. No updates have been made to the project, but sometimes it seems as if there is a “bottleneck” either in Edge or between Fly and Supabase. There is no apparent reason for this, because we have experienced heavier loads before and the response time did not increase that much. The only thing I noticed is that the number of connections to the database increases significantly when there is a delay, and then drops sharply. Perhaps someone else has a similar problem, or the Fly team can give me some advice?

p.s Looking more closely, it seems that when a transaction occurs in the database, the connection between Fly and Supabase simply breaks
