SCEE's confirmed that PlayStation Network is to undergo maintenance later today for a short while.
The service will go down at 3pm, but will be fully online again at 6pm, although Sony says it won't affect PSN activity.
"A small number of user may experience an error attempting to download content during this period and the error message may appear: ’80022f10 – communication with server failed," said a UK community mod on the PlayStation forums.
"If this occurs starting the download process again and this content should go through as normal."
If that doesn't work, hold off until 6pm and try again then, according to SCEE.
