@cwicseolfor @SRLevine about a month ago they said they had something like 9 months of money left to pay for hosting, and implied they weren't planning on shutting the servers down unless they ran out of money. You should have plenty of time to move, but the admins also don't seem particularly trustworthy, given how all of this has been playing out, so I'd move sooner rather than later.

If you move now the transition will be relatively easy, because you can have your account on urbanists point to wherever you go, and be able to retain most of your follows/followers. If you wait until it's offline you won't be able to do that.
