Is lemmy.ml not taking in new users at the moment?

They are overloaded, try Lemmy.world

Have you checked if a user with the same name already exists? Currently it is bugged and doesn't show an error message.

I had to join at lemmy.click

Both .nl and .world were not working for me.

Not sure if this was a problem but when trying to register to certain instances on my phone (Chrome iOS) the ball would spin forever. When doing it on my desktop it was no problem.

I think lemmy.ml is just receiving a huge amount of traffic all of a sudden. Even just a couple percent of all redditors suddenly making an account on Lemmy servers will give their comparatively smaller servers the beating of a lifetime.

What is wrong with yer current instance? There is no real detriment to not being on Lemmy.ml if ye are are already on another instance

I had a similar experience signing up to lemmy.world. I switched to a different password and was able to sign up. However, one of the commenters says that registration at lemmy.ml is closed.
