Your response is unrelated to the message I replied to, which 
asked about the link state algorithm that Cascade uses.  

As far as I know, nobody has announced which set of MCI Wordlcom's
switches were responsible for their outage.  Since MCI Worldcom 
uses multiple types in their network, statements like "goes as 
predicted - complexity bites" is irresponsible at best, even if it 
is later determined the Cascade switches were actually the cause 
of the outage.
