According to the US PlayStation Support site
, the PSN store will be down for "scheduled maintenance" from 8AM - 11PM PST today. The PlayStation Blog
is a little looser with the time of the maintenance, expressing it'll be from early today through the "early morning of Tuesday, April 15." Once the downtime ends, users will be prompted to download a firmware update.
All of this, of course, is in preparation for the new PSN Store going live tomorrow
. We do not believe this behind-the-scenes updating will affect other PSN features such as chat or games, but if something does go wrong -- well, this will probably be the reason.
