Re: [EXTERNAL] Re: VoIP Provider DDoSes

FYI, UTRS (Unwanted Traffic Removal Service from Team Cymru is a free service where you can send a blackhole advertisement (sacrificing the one IP that’s under attack to save the rest of the network) and they will propagate that via BGP to hundreds of other ASNs which will then blackhole traffic to that IP. This can drastically reduce the amount of DDoS traffic that is received by the victim network.


The problem with this approach, and with scrubbing centers more generally, is that while the cure might be better than the disease it doesn’t result in usable VOIP. Voice customers don’t care if things are better but their MOS scores are still below 2.
