A little bit of necro post, but for those of you that don't know QC does have a data center in Johannesburg. Just a pity that the game doesn't get a lot of exposure locally.
The game is now free-to-play since Quakecon the past weekend, so there is no reason why anyone shouldn't check out the game
There is a local site:
