I can't sign in online I dnt no y but says DNS error

Following on from the PS3 3.50 firmware update today, we have started to hear of owners having problems logging on to their accounts.

We have heard of PS3 owners who have updated their system complaining that they cannot sign in, and every time they enter their password are getting the wrong password message. We have had customers who have two PSN accounts and cannot log into either of them. They are met with wrong password message, and even when they use "Forgot your Password" all that comes up is an error.

Conrad Zimmerman of Destructtoid is reporting that PSN is going to have some scheduled maintenance today. This could be why users are complaining of problems logging on to their accounts.

The maintenance is expected to take place during 8 am until 5pm Pacific time. There will be a lot of users who are at work during this time so it will not be a problem for them, but for everyone else it will be somewhat of an annoyance.
