So why isn't su.itunes.apple.com resolving to my close Akamai cluster?

App store content is coming through Akamai, but the failures I'm getting
seem to be coming from an akamaiedge device. (which I thought was
more just a proxy through to Apple rather than CDN, don't know where
the problem may be).

Doing some SSL traces of what my iPhone is doing...

Specificly, https://su.itunes.apple.com/ is timing out in the SSL handshake
during the failures. 

The HTTPS connection failed out for SSL: Received close_notify during handshake

The actual App content for what I upgraded came from 
http://a1128.phobos.apple.com/
http://a1746.phobos.apple.com/

which are Akamai CDN, which hit the MICE Akamai cluster.

All the other Apple URLs seem to work just fine. Its that su.itunes.apple.com
akamaiedge host that isn't keeping up with the load.
