Hey, admin of lemm.ee here. I have no behind the scenes knowledge of what happened to vlemmy, but I have heard (in this thread and elsewhere) that some communities have been suddenly left without a home. I hope it's OK for me to direct a message to such people here.
If you're looking for a new home for your community, and don't want to do it on lemmy.world for any reason, I would be happy to welcome you at lemm.ee! If you're interested and want to know more about how lemm.ee is run, you can check out our administration and federation policy.
We recently upgraded our servers, so should be no problems in accepting some new users. In general, lemm.ee is not going anywhere - we have even already paid for some of our infrastructure up front for a year.
Let me know if you have any questions!
