right, CF (along with Google and Meta) is already servicing double-digit percentages of the world's traffic so it can absorb whatever packets you can toss at it. On the other hand, I suspect most services are going to fall over at L7 first due to common patterns like pre-forked ruby/python servers that struggle to process more than 1k qps per node, unauthenticated user actions putting load on hard-to-scale resources like RDBMS, next to no load shedding designed into the system, etc.
