isn't it about time that the main carriers started allowing BGP community tagging for the purpose of blackholing DDoS targets? Technically, this isn't difficult to do - see http://www.secsup.org/CustomerBlackHole/ which gives examples for both Cisco & Juniper.
Allowing this would help ISPs to achieve a quicker resolution to the problem, without having to get hold of an upstream engineer to put such a block in place (and remove it later). We all end up winning - we get greater control of our networks, and the carriers don't have their engineers tied up on after-hours callouts because a customer is being DoS'd
How effective is it in practice? Any statistics? It occurs to me that if you could spoof the BGP advert you would have a remarkably effective DoS :-) I'll look into it... -- Michael Newbery IP Architect TelstraClear Limited
