It was indeed down for a little while because one of the two nvmes went missing on the host. I’ve copied the containers to a different host before consulting the hoster just in case and stopped them in the process. Luckily it showed up again later so we didn’t have to rely on the already worn out other drive upon reboot that may fail in the nearish future. Check out https://status.tchncs.de/ as in such cases, i leave a note there … and also usually on Mastodon and Matrix at least :)
