GTA V's eagerly anticipated online mode went live yesterday, but unfortunately rather than lots of happy gamers being able to join servers and commence the co-op mayhem. Many gamers encountered error screens which halted their attempts almost immediately. Rockstar has already apologised and set up a support page which they will be keeping updated as they profress with fixing the issues.
The current support page has the following info for stuck gamers.
Question: I'm having problems getting into GTA Online! Is there a list of issues Rockstar is looking into, so I can stay informed about the status of fixes for known launch issues?

It seems that GTA V Online has joined the infamous club of not being fully prepared for the rigors gamers would put on the servers and system as a whole, but thankfully they have been quick to act and hopefully will be just as quick to resolve the problems.
