As usual, the whole "scheduled maintenance" notice seems a bit overboard — as we've never had a problem connecting and playing games online during these periods of "supposed downtime". But it's still worth noting that from 14:00PM GMT through to 08:00AM GMT (Friday, February 3rd) certain PlayStation Network features will be unavailable, such as: the PlayStation Store, PlayStation Home and Account Management.

Supposing you're connected before the maintenance kicks in — you'll be pretty much unaffected though. It's good to be informed, isn't it?
