[announcement] Unexpected Prolonged downtime (was: IMPORTANT: Matrix chat server switchover: need to act || Scheduled Downtime)

Dear Community,

due to technical reasons out of our and their reach, the new matrix
hoster can't finish the migration right now. They expect to finish it
tomorrow. We'll have to ask you to be a bit more patient with the Matrix
chat service right now – our prime objective is to make our chat
infrastructure as rock-solid as possible for GRCon.

With apologies for the inconvenience,
Marcus Müller for the Matrix migration team.
