Unilem.org Offline

Anyone know what happened to unilem.org? It was my main lemmy instance for several weeks, then it just went poof. It's been down I think over a week.

PS. thanks to whoever removed it from the list @ https://join-lemmy.org/instances -- initially I was going to post here to point out that it probably should be removed.

PPS. I did not join that instance because they said they will federate with everyone -- I just saw it in the list and randomly picked it. I only learned about their federation policy when trying to find out what may have happened to it a couple days ago.
