We saw the problem and we have redundant connections to Level 3 in Atlanta.......... On Oct 20, 2009, at 1:31 PM, Bill Wichers wrote:
It's possible the faulty device was an aggregation router and only those customers connected to it saw the outage. Redundancy within Level(3)'s network would not have helped customers with only a single connection off the affected device. At some point it becomes the customer's responsibility to redundantly connect to their upstreams (as in buy two connections on different aggregation routers :-).
I didn't see any L3 issues up here in Detroit, so whatever outage L3 had was apparently contained within that one POP or region. No cascade failures I can see...

Level 3 has a single router or switch handling packets at a major POP? I doubt this, but the outage is confirmation something bad happened.
That said: where's the redundancy, and why didn't it kick in?
