Backbone issues?

18-Oct-2004 21:00 UTC:

We have had several reports of intermittent ISP level latency and "slowness" issues which we believe may be related to what is being reported as a "backbone outage causing routing instability and packet loss" at Level 3. The problems appear to be centered in the U.S. Northeast. We do not currently have any solid information on the cause or the time-frame for a solution, but Level 3 is aware of the issue and actively working to fix it. We wanted to give our readers a "heads-up": If you are experiencing slow connections, it may not be your imagination. We will post additional information if and when it becomes available.

We have received forwarded reports that the issues with Level 3 were centered within their Washington DC area point of presence. These issues caused a cascading effect both within Level 3 and with other providers and ISPs who pulled BGP sessions with Level 3 to contain the problem. At this time, most issues should have been resolved with the possible exception of sites/ISPs within the DC area itself that are using Level 3 as a provider.

Thanks to: Myles, Michel, and Joseph for updating us.
