You do realize that a) there was (and might still be) a large-scale DDoS against PSN and XBL, and b) it's Christmas, which compounds the issue due to the flood of new consoles - the same thing happened last year, though not quite as bad due to a lack of DDoS.
If Sony were to include DDoS mitigation and protection in the price of PSN, I doubt it'd be as cheap as it is now. Anyway, this is a complex issue - I think you might just want to wait a week before coming to a snap decision. It sucks that this happens, and happened, but no company in the world is immune from the kind of DDoS we just saw.
PSN is up for a large chunk of people across all regions (PS3 and Vita appear to be back to 100%), while PS4 is still having issues depending on region, and which datacenter you connect to. I suspect Sony might be bringing things back up slowly, checking for any actual intrusion attempts that might have occured during the DDoS.
