Is domain 'aol.com' protected by a sort of FW

[savron @ world-net . sct . fr]

Trying to download a file from a site in this domain and founding the 
downloading was too slow , I tried to do ping and traceroute .

The result was :

      PING : Destination net unreachable
      TRACEROUTE : stopped at the frontier of  'aol.com' (same as 
above)

    but the download finally came to a completion (successfully)

Could anyone tell me about it ?

Thank you
