Advanced Warning: Qwest/Lucent ATM upgrade

Routing may be weirder than normal this evening.  Qwest is upgrading
their Lucent ATM switches to fix a bug, and needs to shutdown their
entire ATM backbone for a couple of hours.  Qwest hasn't responded to
my e-mails asking what is happening, but other ISPs have outlined
alternative routes they will be using.  Most will try to maintain
service by additional peering, deaggregated routes, or temporary
third-party transit.

Other providers use Lucent ATM switches.  I don't know if they
will also need to upgrade their networks at some time in the future
to fix the same problem.
