Repeated packet loss on AT&T

I have had similar issues with AT&T in NY.  They have peering issues  
with MCI killing random access to random websites, (www.netflix.com,  
www.netbank.com).  I trouble shot it with AT&T a couple week ago and  
they killed a bad link.  It fixed my problem.  Last I knew the link  
was still down and they were looking to repair it this week.
