Very ironic this post is here considering AWS Today.

But just think about it, SE made the FF14 DC for 2.0, in 2013, AWS wasn't exactly insane back then and had a lot of flaws... Azure especially.

You think they're just going to lift and shift their entire infrastructure for an issue that happens once every few years? Login queues are a none issue for the majority of an expansions life cycle... Shadowbringers wasn't bad and you could get on without 2002 (at least EU).

You're basically asking, why didnt they foresee insane success 8 years down the line from an absolute disaster of a legacy, guess they didn't buy a magic 8 ball...
