we have dispensed with 'site' and 'location' as relationships which would define a 'portion of' as a 'root server instance', and that's good (says me).
Personally, I'm not ready to give up on location/site as part of the RSSAC definition for instance. When we're at an RSSAC meeting discussing instances, location is the primary way we identify them. I really liked the plain language Wes used in his recent definitions and i'm concerned your more technically accurate definition will confuse much of our RSSAC audience.
"A root server instance is the portion of a root server operator's infrastructure [dedicated to serving] root data at one [or more] of the IP addresses associated with a root server identifier [and having connectivity disjoint from all other instances of the same server]."
What differentiates the connectivity between C-root's New York and Chicago instances? I assume (perhaps wrongly) that they are both connected to Cogent's network and fall under a common BGP routing policy. To me, you need to use location to best describe that difference. -Karl
