No, I'm pretty sure that this is a third distinct service, not EdteSuite
or FreeFlow - I know it as nothing but AkaDNS, it probably has a "real"
name - if you traceroute to those servers, you'll see that they're actual
Microsoft servers.  Look at that, versus, say, www.segway.com, which is on
EdgeSuite:

www.segway.com.         3600    IN      CNAME   www.segway.com.edgesuite.net.
www.segway.com.edgesuite.net. 21600 IN  CNAME   a1758.gc.akamai.net.
a1758.gc.akamai.net.    20      IN      A       209.185.188.10
a1758.gc.akamai.net.    20      IN      A       209.185.188.107

Notice it's on edgesuite.net, not akadns.net.
