Tonight I deployed a slight update to MirrorManager that I'd been wanting to do for a while. The basic selection algorithm for choosing the order in which to return mirrors to clients remains the same: prefer same netblocks, internet2 in same country if on internet2, same country, same continent, then global, in that order. However, until now, faster mirrors (those with larger bandwidths) were returned with equal probability as slower mirrors. This means not enough traffic was being sent to our gigabit-connected mirrors, and too much traffic was being sent to our slower mirrors.
Each mirror's bandwidth value is now used as a weight. Mirrors with larger bandwidth will have a a higher probability of being returned earlier in the mirrorlist selection. Slower mirrors can still be returned as the first mirrorlist selection because this is based on probabilities, but should not be overwhelmed anymore. For countries with fewer mirrors, such as India, where there's some relatively fast mirrors, and several relatively slower mirrors, this should mean that users will more often get directed to the faster mirrors.
