I've got some more troubleshooting that may help.

You can also try alternate DNS settings with the steps here. If you don't see a difference, try the Google DNS servers. Those are: Primary alt number 8.8.8.8 - Secondary alt number 8.8.4.4.
If your router supports QoS (Quality of Service), make sure it's enabled and prioritize your PlayStation.
On your router, make sure UPnP is enabled. Also, check to see if there's a firmware update available.
You also can contact your ISP to see if they are noticing any issues.
It would also be good to make sure you're using a at least a Cat6 ethernet cable and be sure to check it for any damage. If you're playing on a wireless connection, try switching to a wire.
That's all I can think of at the moment. We're not aware of any issues with our servers and we aren't receiving many reports of disconnecting. Should anything be noticed, we'll make an announcement.
Also, I'm about to head out for the day, but I won't return until the 17th so I won't be able to help with this until I get back, but I really don't know what else to suggest.
