Rockstar has announced Grand Theft Auto Online will be unavailable for roughly 24 hours from later tonight due to maintenance.
It's scheduled to begin at 6PM Pacific / 9PM Eastern / 2AM GMT and will last for most of tomorrow, Thursday January 16. The post announcing the news concludes "We expect to be back up within 24 hours. Apologies for the inconvenience."
GTA V was recently revealed to be the UK's fourth biggest-selling game of all time, which is hardly surprising; upon its release back in September 2013, GTA V became the UK's fastest-selling title ever, and managed to overtake lifetime sales of GTA IV in just three weeks, before going on to secure a stonking seven Guinness World Records. Despite threats from Activision over Call of Duty: Ghosts managing to reclaim some of them, the shooter failed to do so leaving Rockstar's star very much burning brightly.
