There are many decent options for ddos protection in the US and Europe, however there are very few in Brazil and Asia that support BGP. Servers and bandwidth in these areas are much more expensive.
Even though we are already doing anycast to split up the ddos attack, a majority of the attack traffic is now ending up in these expensive areas, and to top it off, these ISPs won't respond to abuse emails. It makes me wonder what the point of these abuse email are and if the regional registries have any power to force them to reply.
