Hi, Skywing. We've had a few DDoS attacks and lots of scans and hack attempts. Some of the DDoS attacks managed to wipe out our front-end. At no point were the route-servers impacted, since we keep them well away from our networks, widely distributed, and vigorously monitored (configs, responsiveness, advertisements). Of course we're not perfect and there is no 100% solution, but we understand the implications of filtering gone awry (especially since we use it ourselves), and spend a lot of time and code keeping an eye on these things. Knowing that no one has a monopoly on imagination, we also have some friends at commercial pen-testers hit us regularly, just to be sure. :) Thanks, Rob. -- Rob Thomas Team Cymru http://www.team-cymru.org/ cmn_err(CEO_PANIC, "Out of coffee!");
