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,, which is on
EdgeSuite:         3600    IN      CNAME 21600 IN  CNAME    20      IN      A    20      IN      A

Notice it's on, not
