Friday night is a crazy night from a load perspective for the mirror infrastructure. I think there’s a substantial portion of the FreePBX universe that tries to update that night. We’ve already been through a number of upgrades to it, but it sounds like we have a few more pieces that need some improvements.
Sorry about the trouble - you might also try pointing to the newer infrastructure (mirror1 is the legacy mirror infrastructure) if you haven’t tried it yet. It’s built in a bit more of a scalable way than the old mirror1 server:
fwconsole setting MODULE_REPO https://mirror.freepbx.org
Best wishes,
