The server was offline this morning because of Kernel and MySQL upgrade. It would have happened faster if the server rebooted cleanly after “shutdown -r now” which it didn’t. So we had to send someone there to reset the machine manually.
We also upgraded Spectrum to support JID escaping. If this works after our tests (there seem to be some problems with clients who don’t support the unofficial % character which is used for @) I write more about this here.
