I wasn't able to login to the forum last night and when I hit login it took me to the alloys.my.com/en user profile that I was logged in to. Apparently it was an issue they were aware of and I assume the downtime was related to that.
No one was able to log in, now it's fixed. There's nothing more to add.
Don't hesitate to join my.com Discord server when the forum is down (see signature).
