Honestly, I'd like to know too. I have no first-hand knowledge here, which is why I was asking about it.

WebObjects has been discontinued, presumably for a reason, and while it was ahead of its time back in the day, it wouldn't be surprising to me if its age is starting to show when trying to deal with the huge amounts of traffic the iTunes Store must handle. But I really don't know. I only asked because I've seen it mentioned in this context before.

I've personally experienced a lot of flakiness with the Apple ID infrastructure though, especially with 2-factor auth enabled (their old 2-factor auth, not the new system which I haven't tried yet). Most recently when trying to purchase AppleCare after the fact, I just couldn't log in. I have no idea what's going on behind the scenes.
