Well, I had the "ghost update" that generally accompanies the glitch. I don't really think that would count as a real ghost update though. The page will always show an "application/profile updated" message if you're about to get a Bad Gateway error—from what I have learnt, this is somehow triggered by the error, but of course, it could coincide with an actual update. Which is why I like to come on here and check if others are also experiencing the error at the same time or if it is just me.
If you want to drive yourself crazy (I like doing that to myself), then anecdotally, I can confirm that at least twice I have had a glitch-related "ghost update" coincide with an actual update. So if you want to desperately seek hope (like me), then you might like to pretend that an officer updating your file in the background is causing your portal to temporarily act glitchy at your end. Good old speculation!
