It looks like there’s certain hosts that are designed to load balance (or something) between a few IPs, regardless of geography. For example pbs.twimg.com resolves to wildcard.twimg.com which returns two different IPs each time, from a pool of 5–6, at random. Basically rolling the dice whether the client and the proxy are going to get the same IPs at the same time.
