Question about the 11/10 update

[SaitoHikari]

Yeah, I want to speculate that the DDOS wave might have been related to FC chests as well, and experience from other games tells me that there's only one illegitimate reason people would want to mess with FC chests in such a fashion - an attempt to duplicate items.

Something similar happened a lot in MapleStory with how player inventory and player storage worked, along with the 'cash shop currency market' storage. If a massive DDOS wave hit the game, it was a safe bet that people were trying to duplicate items by forcing rollbacks on their inventory. This was pretty much common knowledge due to how often it happened, and hackers openly bragging about doing this with no repercussions. The devs were eventually forced to axe the 'cash shop currency market' entirely to stop this from happening.

Of course, FFXIV's infrastructure is likely much stronger for the devs to detect such a thing happening quickly, and to implement a potential hotfix without taking down the entire game.
