Anyone else notice the sj-download.cisco.com is slow?

 

Second try at downloading 7.1.2a, first try the file sizes were too
small and checksum didn't match;

 

 

 

Why is cisco.com so slow? I downloaded FireFox 3.5 at 3MB/Sec, and
VMWare Workstation 6.5 at 1MB/Sec.  I have a 8MB Cable Modem.

 

Second try is a failure too....
