The problem Sony is having is FAR bigger than end users changing their MTU size. This post was intended to help people get on PSN. I'm sure the login system is clogged beyond belief right now and the IT guys (me) are working their asses off to remediate server after server after server. A few people changing their MTU size is the least of the PSN issues, so the people saying this caused another outage can take a Midol. Peace Out
