Ping is faster than speed of speed? How to ping original webpage
===

I live in Warsaw, Poland. I am pinging any US webpage (like www.nba.com):

   

    $ ping www.nba.com
    PING a1570.gd.akamai.net (213.155.152.161) 56(84) bytes of data.
    64 bytes from 213-155-152-161.customer.teliacarrier.com (213.155.152.161): icmp_req=1 ttl=58 time=6.90 ms
    64 bytes from 213-155-152-161.customer.teliacarrier.com (213.155.152.161): icmp_req=2 ttl=58 time=5.68 ms

Time that I receive is around 7-10 ms, while distance from Poland to US and back (packages go forth and back) is around 16000 km (16*10^6 m). c=3*10^8 m/s. Distance/c = 0,05 s = 50ms.

So I suppose, that some webpages are cached on some other server e.g. in Western Europe (5ms, means less than 750km from my place). How than I can ping the original, US webpage then?

Or did I miss something?
