Savvis has this fun way of asymetrically routing. Try mtr from master to
you, it will be different. This IMHO is one of the leading causes of
troubles. We can't do anything without some hard reproducable evidence
then we can bop the savvis people and they will fix it.
Incidently, master->va has been clocked at over 200kbytes/sec so the
connection does have physical bandwidth.
