Back when working in a DSL based national ISP in Australia, based in
Brisbane, there was an extra 30ms or so from other side of country (Sth
and Western Aus in particular), anycasting our caching servers in those
other states PoP's, made a world of difference to them, how one can just
rely on 170-200ms is beyond me, it would be worse than going back to
2400baud dialup days.
