NAC is not a global intercontinental super-duper backbone, but we do the same. It takes some education to the customers, but after they understand why, most are receptive. Especially when they get DOS'ed. On Thu, 28 Aug 2003 variable@ednet.co.uk wrote:

We have a similarly sized connection to MFN/AboveNet, which I won't recommend at this time due to some very questionable null routing they're doing (propogating routes to destinations, then bitbucketing traffic sent to them) which is causing complaints from some of our customers and forcing us to make routing adjustments as the customers notice MFN/AboveNet has broken our connectivity to these destinations.
We've noticed that one of our upstreams (Global Crossing) has introduced ICMP rate limiting 4/5 days ago. This means that any traceroutes/pings through them look awful (up to 60% apparent packet loss). After contacting their NOC, they said that the directive to install the ICMP rate limiting was from the Homeland Security folks and that they would not remove them or change the rate at which they limit in the foreseeable future.
What are other transit providers doing about this or is it just GLBX?
