All Matrix services will be offline for maintenance starting on Thursday 31th Aug 2023 in the morning around 06h00. Minimal downtime is 1h, but some bots/bridges may take longer.
The host system will be upgraded from Debian 10 to 12, followed by an upgrade of the database (PostgreSQL 11 to 15) and ~20 application servers.
phys.ethz.ch homeserver (people accounts)
First priority is the
phys.ethz.ch homeserver hosting our accounts and rooms. Estimated (best case) downtime ~1h.
Your Matrix clients (Element) will show connectivity errors during the downtime:
mbot.ethz.ch homeserver (bots, bridges)
Second priority is the
mbot.ethz.ch homeserver, all bots, bridges present in the #mbot:phys.ethz.ch room and anything else. I expect most to be back after another few hours but Thursday evening at the latest.
The deprecated webhook bridge will be put out of service.
The ETH homeservers
studentchat.ethz.ch are not affected by this downtime.
Alternative: jitsi.phys.ethz.ch video conferencing with integrated chat.
