SONY's Successful playstation 3 network is shut down for maintenance, why?

It could be one of these:-

1-An error on the internal clock thinking it has leaped through a year, which sets back the date to the last day of 1999, and to some people the first day of 2000

2-A Canadian hacker messed with the update, why did I say Canadian? Because there was a hockey game between USA and Canada and I think Canada lost( My friend told me they won that's why I said I think)!
What could it lead to?

1- The loss of every data you have on your system!

2-nothing!

3-Dynamic themes being corrupted!

Should we destroy the ps3? NO, this is just caused due to the ps3 being retarded on the 1st of march!
