Lizard Squad have been attacking PSN and Xbox Live this Christmas and the networks are slowly coming back to full capacity. However, if you can’t login to PSN we have a workaround that is guaranteed in most cases to work.
Many people are online right now on PSN and if you are one of those unlucky ones who can’t log into the service then you have to do this to get online.
Go to network settings and set up a new connection. Select manual and when you get to MTU, select 1473.
This should be enough to get you into the service. Also if you can’t login to Destiny the best workaround is to mash the X button till it says signing in.
Let us know if it worked for you or if you have another workaround.
