The PlayStation Network service will be offline tomorrow evening in Europe between 17:00 and 23:00 UK time due to maintenance, Sony has announced.
During these hours, PlayStation 3 and PlayStation Portable gamers will be unable to access the service or play games online.
Players can get around the disruption by signing in before the maintenance begins. Players who are already connected should find their gameplay unaffected, Sony said.
Access to the PSN Store, plus account registration and management options, will be unavailable to all, however.
Is Sony beefing up its security? The company yesterday unveiled the hiring of ex-US Department of Defence man Philip Reitinger to help combat the threat of hackers.
