Yeah I've got the same problem too. If it is maintanence Sony sure knows how to pick the dates and times.
This is on error code information thread
8071053D - Hard boot the PS3, turn off the PS3 to stand-by, flip off the back swtich and remove the power cord. Then shut off your modem/router, for about 5 mintues, then turn the modem back up first and let it sync, then turn the router back on(if using one) and let it sycn. Reconnect your power cable and flip the back swtich up again. Then make a new network connnection.

ITS A SONY PROBLEM LOOK TOP RIGHT http://uk.playstation.com/psn/ PlayStation®Network Offline
everyone ignore people who say turn off this reset that it wont fix nothing when sony turns it off they turn it off to fix things on the ps3
resetting ur router or pulling plug putting it back wont fix it it will stil be offline till sony fixes it
