Is it just me? :/

Same here. But, it's not the first time it's happened.

If you go to the top left and click on the ManiaHome button, it fails to load there as well. So yes, it's down.

I've reported the issue to Nadeo.

down too.

It's back.

I dont know if this was a coincedence or not, but I noticed that it was "down" when I opened the game by running an 'install and play' link - i.e. if Mania Planet was not already open and I clicked the link then once it had started there was no Mania Home as per your screenshot, but when I closed the game and re-opened normally then the home was back up and running there. This happened a couple of times, so now I always open the game first before using the 'install and play' hotlink.

I think they take down the server sometimes, to improve it
Just as Forzaa do sometimes but that almost not noticable it take 1 or 2 sec
am i right forzaa

@Jonkster. Maybe it just another bug..
