Global Crossing issues?

Wed Jan 23 17:33:00 UTC 2008

At present we aren't seeing (or at least hearing about) issues. 
However, over the last 6 months we've had about 10 different instances 
where connectivity specifically between Comcast and GBLX has had extreme 
problems.

We ended up changing all our Comcast traffic to other providers, but 
unfortunately, Comcast still seemed to heavily prefer GBLX for our 
inbound, and it didn't resolve the problem.  Ultimately, we had to stop 
announcing prefixes to GBLX to get Comcast to use another inbound path 
and all problems ceased.
