Hmm decent points, a lot of the info about Migoland still remains a cloudy story. But the game isn't down because of domain problems. Migoland domain still works as you can still access the site.
They have shutdown the server that holds all of their domains data, my guess is that they are using Migoland servers to run FriendBase.
From info I have gathered from Playdo AB and other leaks suggest that even if Migoland returns, player data will not be available. Meaning that everyone's beloved accounts have been deleted.
