Sony reporting, “intermittent issue with PSN”. 80023102 error reported.
UPDATE: Sony have tweeted that normal services have been resumed.
The PSN is apparently having a few problems at the moment with many users getting stuck on sign in. Sony have issues a statement regarding the issue. Short version: it’s broken and we’re shaking it to see what falls off.
The longer version, posted on the eu.playstation.com forum, reads:
At the moment PlayStation®Network is currently experiencing issues and some users may encounter problems with network services and the store.
(An error code e.g. 80023102 may appear when trying to sign in)
Engineers are currently investigating the cause of these problems, and I will update here when more information is available
