Rockstar's working around the clock to solve the problem.
Yes, the launch of Grand Theft Auto Online has had some problems, and Rockstar has issued an apology "for any inconvenience" as it asks for your patience. No, Rockstar doesn't have a solution, but asks you to pay close attention to its Updates page for future solutions. There's just too darn many of you, as Rockstar itself admits. "We are working around the clock to buy and add more servers," it says, "but this increased scale is only going to make the first few days even more temperamental than such things usually are."
There are all kinds of known issues, from the dreaded Cloud Servers Unavailable message to game freezes, job loading errors, mission failures as soon as the mission begins, and other fun and exciting problems. The spread of comments on the Rockstar boards suggest some of the issues may be regional; PS3 owners seem to be having slightly more luck, but not by much.
Rockstar asks that anyone who wants an automated email advising them of updates and solutions should "please log into the Support Site and click Subscribe at the top of this page."
