Re: anycast stability experiment

[Daniel Karrenberg <daniel.karrenberg () ripe net>]

The RIPE NCC dnsmon (http://dnsmon.ripe.net) has collected such data for
all root servers from dozens of places for about two years already.  You
are welcome to the raw data.  NB: The further back in time the more work
it will be for us to dig out raw data. 

Differences to your set-up:

- most probes are not near the "edges" of the net, for most definitions of "edge"
- probing times are properly randomised
- the mean probing interval is 60s
- UDP only

[Continuous but not scientifically rigorous examination of the data
shows that your bet is a pretty safe one. In other words: for practical 
purposes routing is stable at all proble locations. So the data is 
in fact pretty boring. If it weren't as boring, k.root-servers.net 
would not be anycast the way it is.]
