As was reported when Qwest did the software upgrade to all of their Lucent (Ascend) 550s, the Qwest IP net does not use ATM. It is entirely POS. As a result, the Qwest IP side was not impacted.

This does look like the sort of like the cascading PNNI routing problems that the big upgrade last week was supposed to have fixed. I think the Lucent folk still have problems to deal with.

Folks have reported that qwest said the cause for the failure was an OC48 going down, which led to instabilities within their network.
