Hello, dear Nanog Community! I'm looking for upstreams with BGP Flow Spec / RFC 5575 support in US (West and East coast are welcome). We have implemented support for BGP Flow Spec traffic filtering in our own open source DDoS detection toolkit and using it on our own MX routers. Works really well. But we are experiencing so much attacks on channel overflow and want to lock part of traffic on upstream's side. Thanks! -- Sincerely yours, Pavel Odintsov
