The PSN is currently down. We have just got word that on 08.26.08 (tomorrow) between 8:00-13:00 PDT the PlayStation Network will be down.
We are skeptical, but this "Scheduled Maintenance" may be pertaining to the Home Extended Beta, or possibly even Life with PlayStation. This latest rumor would add up with the rumor we have http://feedonps3.com/?p=80. Only time can tell what is to come.
Also, the Metal Gear Online site has posted an update stating:
PSN Maintenance 26.08.2008
Maintenance will be undertaken on the "PLAYSTATION(R) NETWORK" between August 26th 16:00-21:00 (BST). During these times, customers may be momentarily unable to connect to the PLAYSTATION(R) Network. Please try after some time should this happen.
