A while back the QuakeWorld players Mushi and Dirtbox initiated a quite ambitious project to increase the amount of QuakeWorld servers in the world. Not only did they think there should be more of them, but they have also done certain investigations as to whether there are specific locations that are particularly advantageous with regards to routing, so players in these areas can take full advantage of the re-routing feature QWfwd available in QuakeWorld. In the best cases, this can decrease the ping not only within the community, but also bridge the gap between two communities.
One example has been the start-up of some North American servers that decreased the ping to Europe. Another important recent addition, with help from Claw, is a bunch of servers located in South America. These babies bring down the ping below 50ms between Chile, Argentina and Brazil. This should be a good step to once again unite the South American players on the same battle grounds. If you're from this area, then make sure to try them out!
