While a lot of users were trying their best to reset their password after Sony rolled out the latest firmware update. Sony has pulled out the official PSN website for maintenance. According to official statement made by Sony:
Fortunately we have got ISPs to release outstanding emails; unfortunately, a small amount of maintenance is required to improve this process
So those guys who were anxiously waiting for their password reset email or those of you who just got it and were about to change password, we truly feel sorry for you.
It is important to note that this doesn’t effect PSN on consoles, it is only for the PSN website.
