The extended maintenance period is being used to implement additional changes to backend systems, the game’s Twitter announced.
It said: “We will be running a one hour server maintenance period on live servers to implement additional changes to our backend systems.
“The maintenance will start Dec 6 6PM PST / Dec 7 3AM CET. Thank you for your patience.”
Fans were livid on website Down Detector as access to seemingly the most popular game in the world is cut off.
One user wrote: “Finished my match and it said I needed to update to keep playing. Did it, and now I cant connect to the game.”
Another said: “This game is the worst.”
A third declared: “Just updated the game now I cant connect to the server.”
Last month it was announced that PUBG is in development for mobile platforms after developer Tencent confirmed the port.
No release date has been announced, nor has the way in which the game will be adapted for smartphones to allow a similar gameplay experience.
The developer did disclose that the mobile version will release in China first – a worldwide release would surely follow soon after if the game replicates the same success as its PC counterpart.
PUBG has sold over 20million units worldwide.
The hugely popular title will also be heading to Xbox One on December 12 and will be available through the Xbox Game Preview programme – despite the huge player base, the game’s development is not officially complete.
There is currently no word on a PlayStation 4 version of PUBG despite Sony having a firm lead in console numbers compared to Xbox.
PUBG is a multiplayer online battle royale game developed by Bluehole – the game is focused on player versus player action with battles with up to 100 players taking place.
