[AusNOG] Checking peering

Tue Sep 9 17:43:51 EST 2014

May I ask, how is a blackhole on the internet typically detected by such an
appliance?

It would seem a pretty difficult task in an active/active ISP environment
where a fair amount of traffic is asymmetric (ie both upstreams will appear
impacted just based on traffic levels without some pretty sneaky PBR/static
routing and geo based KPI monitoring)

Cheers,
Matt
