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
Apparently big company disease has taken over. Part of Qwest is telling customers it is working very hard to make this change as fast, and as painless as possible. The other part of Qwest is telling customers, Duh, never heard of ATM. As best I can tell, if you are buying Qwest "IP" service, this won't affect you. If you are buying Qwest "ATM" service, it will affect you. Of course, carriers buying dark fiber services from Qwest will not be affected by whatever shenigans are going on at layer 2/3/4/5/6/7. As always, your Qwest salesperson should be your best source of information.
