Looks like it was an attack.

Only 5% were supposed to have been affected by the outage, so everything is fine, right?
I'm kind of surprised they admitted to being successfully attacked.
Though I guess they had to choose between admitting to buggy software, or being susceptible to attacks.
If these kinds of problems continue to happen do you think Ubisoft will back down, or just keep sinking with the ship?
