From the US PS Blog:
Sony Computer Entertainment will conduct system maintenance for PlayStation Home on Thursday, December 18, 2008. At this time PlayStation Home will be updated from ver. 1.03 to 1.04. The system maintenance is scheduled to start at 12 midnight (PST), and the service is expected to resume in approximately 6 hours but may change depending on the circumstances. PlayStation Home will be unavailable during the maintenance window.
The reason for this maintenance is to ease the difficulty some people are having accessing PlayStation Home due to the high demand for the service.
Additionally, as part of version 1.04, the voice chat feature within PlayStation Home will be temporarily suspended. As soon as we are ready to resume the voice chat feature, we will inform you via PlayStation.com and PlayStation.Blog. In the meantime, we encourage users to make use of the Wireless Keypad for PLAYSTATION 3 or any USB or Bluetooth-enabled keyboard for text chat and also the “phone friend” features to communicate within PlayStation Home.
We apologize for any inconvenience this may cause you and kindly ask for your understanding.
