To me this looks like a problem with 42live's backend systems and unlikely to be anything at the ground. Given the broadband speeds quoted that people get it's unlikely the buffering would be at the users end. 42 Live's service would be shared across multiple servers and maybe locations, whether you get a good stream or not may have been dependent on which server or location you happened to be directed to. Which servers and location you get directed to would also be dependent on your location so Australia and South Africa may have hit servers with only a few on where users based in the uk from the same brodband supplier may have all been fighting for the share of a server/network which couldn't cope.
Time for 42Live's NOC to earn their corn then
