So yea, I noticed something when the attacked occured, and if im just being an idiot and dont know what im talking about, plz dont rage, im just tryin to help. Well anyways, I was hosting a server when it happened, and the same IP tried connecting and failing to connect until I shut it down. SO, anyways... Here is is. 69.175.14.242 If you want the entire error ill paste it in here.
If that was an I.P. trying to take down notch's server, it would be more likely that that was a semi-innocent infected computer that the hacker was using to attack with.
