Horrible experience in South Delhi - While speed tests and a few sites work fine (@4 Mbps), online gaming is terribly frustrating. Moreover more online video streaming sites (except for youtube) are slooooooooooooooooooooooooow (i.e. about 128Kbps to 1.5Mbps though usually closer to the former). I know that CC will say that they only guarantee speeds till Airtel's servers, so haven't even bothered calling them.
