Darling companies of this very website have mistakenly brought down large portions of the internet thanks to our old friend BGP. No attacks required, just small oversights and unfortunate concentration on the business/IP space! This happens regularly.

Anyway, to your point, things can be resilient. They tend to be or not be... because we made them that way. Don't poke your bruises, and all that. Life support is deployed on-campus but relies on a single-point IPSec tunnel to us-east? Easy fix: stop that.
