Caching servers in Local ISPs !!

[itpp2012]

Its quite simple, think of it this way, a DNS entry does not have to point
to the same IP everywhere.

Place your cache machines at a ISP, have them assign its IP to your
preferred dns name, thats about it.

The rest like distribution works like a reverse riverbed with a master
mirror, rsync or the likes.

And of course this can all be done with nginx at all locations.
