PSN is down or is it my account? – NeoGAF

The internet is a series of tubes and sometimes those tubes get clogged, but really it’s likely something temporarily down between you and PSN. You could try resetting your equipment or changing DNS servers off your ISP, which I would do anyway. If you can connect fine via mobile then you can at least have the peace of mind your account is fine.
