Might have been targeted by grumpy fans.
Minecraft has fallen victim to a distributed denial of service attack according to creator Markus Persson, although the developer is at a loss to explain why.
“Denial of Service means you occupy certain resources for a long period of time, making other people not able to use them. A real world example would be running up to the cashier at a super market and paying in small coins, counting every single one really slowly, then finding out at the end you didn’t have enough in the first place,” Persson, who goes by the name Notch, wrote on his site.
“As to why minecraft.net is being targeted, I’m not sure.”
