Starts: Tuesday 14 October @ 20:00 BST / 21:00 CEST
Ends: Wednesday 15 October @ 01:00 BST / 02:00 CEST

During this time, you will not be able to sign in to PSN
We apologise for any inconvenience caused.http://community.eu.playstation.com/...ead.id=1023768

2PM - 7PM EST / 11AM - 4PM PST

The Playstation Network will be down for 5 hours on October 14, 2008.

Quoted from Joystiq: "After we were tipped about "essential maintenance work" being conducted in Europe on the PSN, we contacted Sony to find out if North America would be shutting down for a time as well. Turns out, it is. The PSN is scheduled to be unavailable tomorrow, Oct. 14, during the following time:

• 11AM - 4PM Pacific
  
• 2PM - 7PM Eastern
  

Be sure to plan accordingly and get those petitions ready demanding a refund for the downtime."
