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.
