MTU is maximum transmission unit and 1500 is commonly used by hackers to send something called a ping of death. This was probably used by the hackers that took down the network and Playstation Network engineers have probably set the MTU acceptance lower than this to not allow that size packet to enter their servers network interfaces. To be honest, this probably should be default on any server to mitigate the threat of a ping of death, short of not allowing pings at all. In the past multiple pings of death set to 1500 bytes could take down a server with no problem on interfaces where a max speed of 100 Mbps were present. However, in this day in age with interfaces that can handle Gbps it would take quite a bit of bot machines to accomplish this. This, in my opinion, is what Lizard Squad used to take both networks offline. Although, this type of attack is not very common anymore unless you have enough bot machines launching the attack at one synchronized time. Which probably was the case!
