Seems like the problem has been confirmed to be Savvis. In some places 
Akadns is returning real Akamai sites with correct routing:

download.microsoft.com is an alias for main.dl.ms.akadns.net.
main.dl.ms.akadns.net is an alias for dom.dl.ms.akadns.net.
dom.dl.ms.akadns.net is an alias for dl.ms.d4p.net.
dl.ms.d4p.net is an alias for dl.ms.georedirector.akadns.net.
dl.ms.georedirector.akadns.net is an alias for a767.ms.akamai.net.

In others it is returning download.microsoft.com.c.footprint.net:

download.microsoft.com is an alias for main.dl.ms.akadns.net.
main.dl.ms.akadns.net is an alias for dom.dl.ms.akadns.net.
dom.dl.ms.akadns.net is an alias for 
download.microsoft.com.c.footprint.net

The footprint.net CDN appears to be updating every minute or so with new 
data, each more broken than the last. So far this morning I've also seen 
(from various places not near any of the final sites):

cdn-colo.Frankfurtfrx.savvis.net 90.626 ms
ge-0-0-1.a20.taiptw01.tw.ra.verio.net 197.312 ms
so-2-0-1-0.par22.ip.tiscali.net  82.875 ms
iadvantage-1.gw2.hkg3.asianetcom.net 238.817 ms
xe-0-1-0.a20.osakjp01.jp.ra.verio.net 271.745 ms
bcr1-so-1-0-0.Londonlnx.savvis.net 167.918 ms
cpr2-pos-0-0.VirginiaEquinix.savvis.net 90.493 ms
ae-11-51.car1.Atlanta1.Level3.net 149.736 ms

If you really want to download something from microsoft at faster than 
crawl speeds, try moving your resolvers around to find a nameserver that 
is getting real Akamai results. Otherwise, wait for Savvis and/or MS to 
get their act together. :)
