Thanks for the posting. How come they couldn't access their routers via
their OOB access?
My speculative guess would be that OOB access to a few outbound-facing
routers per DC does not help much if a configuration error withdraws the
infrastructure prefixes down to the rack level while dedicated OOB to
each RSW would be prohibitive.

Thanks for sharing that article. But OOB access involves exactly that -
Out Of Band - meaning one doesn't depend on any infrastructure prefixes
or DFZ announced prefixes. OOB access is usually via a local ADSL or
wireless modem connected to the BFR. The article does not discuss OOB
at all.
