I think I remember something about the Libera IRC connection being
rate-limited?


There are several different delays occurring.
1. Currently we are generating a lot of  different notifications for EPEL-9 setup and branching. This affects general notifications with delays
2. there is a major delay happening between IRC and Matrix wherever that pass through happens. Messages are generated in IRC and will take a while to shift over to the matrix side. [Vice versa does not seem to have a similar delay which leads to some weird conversations]
3. There are a lot of 'dead-accounts' and 'full-accounts' on Fedora lists and tools. Ones that go to gmail will cause google to throttle any email going to all gmail.com accounts for hours if delivered from a mailing list like the various notifications ones or devel etc. It used to be mailman and various tools would unsubscribe people but that odes not seem to be happening for whatever reasons. I have been just having to do manual unsubscribes from lists when I have time to.

There used to be some problems with notification tools in the past where they would crash, then ask for a lot of old messages to make sure they were done, then send a couple and crash again and... but I don't know if that has been fixed in the last 9 months since I left Fedora IT.
