This has been going on since the big update a couple of weeks ago.
Basically every time I try to do something on this site, it takes 10 minutes to load and then I get a screen (or a popup) that says Error 503 and something along the lines of "backend fetch failed."
The reason I haven't reported it sooner is because I finally figured out that it's not my home internet or even my phone, it happens regardless of where I am or if I'm on a phone, tablet or computer.
Does anyone else have this happen to them?
