Norton Blocking Itself (IP 63.245.201.112)

I recently re-installed Norton for the Mac and got an intrusion warning.

Connection Attempt Incoming Denied, Suspicious Activity, TCP, Remote Address 63.245.201.112, Port 80, Host sapi.norton.com, Local Port 49752

I did a trace route:

traceroute to 63.245.201.112 (63.245.201.112), 64 hops max, 72 byte packets

And then I checked it out here

And it all looks OK.  So maybe I am a bit too paranoid.
