The recent DDoS attack on FFXIV servers.

[Nestama]

Like.....who's benefiting from doing this attack?

I don't think they care, though they'd likely give you a nonsense reason. Possibly similar to whatever that group is called did with the PSN servers a few years back on Christmas ("we did it so that Sony would work on strengthening their servers to prevent DDoS" or some stupid nonsense like that).

It's really just to be a pain in the neck and maybe make customers angry at SE. S'how I see it, anyway.
