What is going on with the Darwin machine with IP address 2001:bc8:38ee:100:6666::2? I still cannot reach it (SSH times out and it also doesn't react to pings).
aloisw: is that the same as m1@build01.aarch64-darwin.lix.systems? if so it's currently down for unknown reasons and needs a manual reboot, discussed here: https://zulip.lix.systems/#narrow/channel/7-T-infra/topic/SCW.20macOS.20seems.20down
