I won't believe a company like Level3 would not deploy backplane
protection/policing on routers. Also, 1Tb/s aggregated DDoS towards OVH
network didn't pause or rebooted routers. And i guess both companies have
had their share of (D)DoS in the past, so they had the time to get up to
the challenge. Now... there where times where one malformed IP packet would
cause a memory leak leading to a router reboot... :)​
