Getting a 504 every time for 3 days now.
P2P is working for me now. Can you confirm if it's up for you? Probably part of the overall site lagginess for the event. :(
I get issues with this with specific users. Like with some people I am able to view P2P comments with them no problem, but other specific users I click to view P2P and it just will not load no matter what. Constant 504 error no matter how many times I try, how long I wait, how many days later. It just never works for them ever, even when it's working just fine for everyone else.
