These are either proxy servers or active cache servers in a global
cluster like akamai technologies uses (yahoo, cnn, altavsita) etc, etc. which are used for global loadbalacing... if a user goes to yahoo his shortest/fastes path is determined by BGP router info
and a distributed DNS gives out an IP of the best location for that
user.
works a bit similar as flashing proxy. I would not worry about it.
