Since it's taking some more time, and I realized there's also a mastodon update that'll take another 30 mins to apply, I figured I'd open this status page.
We're almost back up with most of the base services, the server's main OS updates and reboot was already done and we've been running updates on the individual containers/services, which is well underway and should be done in <10 mins.
After that's done, Mastodon's update will start.
