Re: Antwort: Re: [address-policy-wg] Re: RIPE Access Policy Change Request to allow allocations to critical infrastructure
From my observation on this discussion there seem to be no other parties beside TLD operators that are currently so much interested in setting up anycast services. At least, nobody said so on this list. Some DNSBL operators are definitely interested.
DNS Black Lists are part of the crtitical email infrastructure. Someday a bogon routeserver service like this one: http://www.cymru.com/BGP/bogon-rs.html might want to use anycast. It is part of the critical routing infrastructure. It would be good for the policy to be based on the principle of supporting fault tolerance for critical infrastructure and then it can have a checklist of indicators like TLD operator, anycast implementation, freely available service and so on. It is a good idea to have a checklist that makes the policy easy to implement by the hostmasters, but it is also a good idea for the policy to have a clear foundation statement to cover anything that was not considered in the checklist. --Michael Dillon

They are, but they are not even using the amount of redundancy available by DNS today (read: "as many name servers as fit into a minimum sized UDP packet full of glue"). So there is hardly an argument for doing anycast.

The route servers use TCP, which will not work over anycast (in the general case - consider load balancing, every other packet going to a different destination machine.
