It was a lot worse this morning. By chance are you using custom DNS servers in your network settings? I was using Google's public DNS servers and switching back to my ISP's default seemed to help substantially but something is still not right. Lots of dropped connections during the game. Basic traceroutes from my machine to app.roll20.net were normal so I don't see any obvious routing issue. Oddly enough, one player had zero issues logging in or staying connected so I'm a bit confounded on what the problem could be. EDIT: it does appear there is an issue with Google services, especially for customers on Spectrum internet. I'm not sure how much, if any, of Roll20's infrastructure relies on Google. I think most game stuff uses AWS.
