[NBLUG/talk] Comcast slow downs

A new wrinkle:  This weekend whenever I downloaded an Ubuntu update or used
Synaptic to download a package, the download went at a crawl, often 
1Kbps.  While
this was going on, I tried speedtest.net several times and it reported 
that my download
speed was anywhere from 4 to 6 Mbps.  Does this indicate that Comcast is 
throttling
the sites being used by these Ubuntu downloads?
