It's not uncommon at all to have a single interconnect between providers in a geographical area. Multiple interconnects within a region tended to be more for load balancing, not redundancy. There have been certain providers that, historically, could or would not support anything larger than an OC48. In those cases you had multiple circuits to maintain traffic balance. When they finally migrate to 10GE you back off to a single circuit and use your backbone for city redundacy. -Steve On 11/9/06, Deepak Jain <deepak@ai.net> wrote:
Does someone know if this is a *single* link down?? It seems bizarre to me that there would only be a single link (geographically) between those two.
Whatever happened to redundancy?

We received confirmation from Time Warner. The link between Sprint and Level3 Networks is down in Chicago. This has been an issue since 3:10 PM EST. Time Warner has a ticket open to address the issue. Not sure what it is yet.
