It's not Lizardsquad. I can create an account on Twitter claiming credit saying who ever has taken down the network. It's just some asshole who saw that the network was having issues and so he jumped on Twitter saying it's Lizardsquad. Notice all the tweets were several hours later the first complaints. Lizardsquad would have said several days ago that they were gonna take it down to prove that they are capable of doing it.
