"cp401489-vh.akamaihd.net" is just a CDN's server hostname; 
it doesn't point to a unique physical server, only.
You can read more about CDNs and Akamai at: 

https://en.wikipedia.org/wiki/Content_delivery_network

https://en.wikipedia.org/wiki/Akamai_Technologies

So, depending on client's actual location, 
different clients may be served by different nodes 
(PoP) of the CDN - at least this is how I 
interpret it, not being a networks expert, of course ;-(
