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. https://research.fb.com/wp-content/uploads/2021/03/Running-BGP-in-Data-Centers-at-Scale_final.pdf
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.
