When vlemmy.net disappeared (and it was the only one I had registered to), it registered at lemmy.world, sh.itjust.works, and while thinking I was registering at lemmy.ML, I registered at lemmy.NL. (then I requested a login at lemmy.ml, but never got a confirmation).

At the moment lemmy.NL is the only instance I have a login at that I can use.

That was a happy mistake :-)

Maybe the problem is me. If lemmy.nl goes down, I’ll know for sure.
