I had a forum page open and was refreshing to see if there were any replies and on one refresh a few moments ago got a 404. I then saw that I was logged out, and when I tried to log in it said it didn't have an account with my address; going to the forum page itself showed completely blank forums (i.e. no posts in the forum sections). A minute later everything was back to normal - I was logged in and the forums were fine.
Is this a problem on my end? Should I submit a bug report? Is the world ending?
