As one of our Community Heralds told you in the Official Discord, the servers seem to be down currently. Just to make this clear for anyone coming here and wondering as well. Might even be back up as I write these lines.

Edit: Well, definitely down. Patience!

I wrote this post here before finding the discord channel and thought it will go faster there, as it did.

The servers are back up, FYI.

I have this problem for a few days. Are the servers still down?
