Good luck with that. 😊 As Damian Menscher has presented at NANOG, even if we do an amazing job and shut down 99% of all DDoS reflectors, there will still be enough bandwidth to generate terabit size attacks. https://stats.cybergreen.net I think we need to instead collectively focus on stopping the spoofed traffic that allows these attacks to be generated in the first place. -Rich

We are unable to upgrade our bandwidth in those areas. There are no providers within our budget there at the moment. Surely there must be some way to get them to respond.

I've tried sending emails listed under abuse contacts for their regional registries. Either there is none listed, the email is full, email does not exist, or they do not reply. Same results when sending to whatever other email they have listed. Example Networks: CLARO S.A.
