updating apt sources...

[Chris Stockwell <doctorstockwell@yahoo.com>]

Hi,
I "could not connect to debian.oit.umass.edu:80 (1.0.0.0), connection timed out
Err http://debian.oit.umass.edu stable/main Release

I am very confused here.  My nic's work fine (I can ping, surf and even got 
one apt source to come up), but now it won't apt-get update, or update apt 
sources at all.  I'm accessing the net via dsl, through a router here in my 
home.  I've edited my /etc/apt/sources.list file a whole bunch with current 
mirrors.  But except for the one time it briefly went through....nothing.

I don't really know what information to provide to have someone help 
me..... but I need help please.
Thank you.
