A number of my players and myself (in different countries across the planet), have experienced an increase in the number of errors reaching the site.  Commonly we're getting 502 Gateway Errors -- often when trying to load a thread in a game; getting into the main page of a game doesn't seem to be a problem.

Is this a known issue?

It should be resolved now :) It was caused by a DDoS attack:

Thanks!
