I didn't say anybody's going to mirror COM, I said I suspect zone mirroring will find applications other than pre-caching the root. The fact that it isn't a complete solution to the problem space you're interested in at the moment doesn't mean it was useless. That wasn't a major motivation for the work anyway, I don't believe -- my recollection is that it was mainly about reducing garbage traffic, with latency reduction for some resolvers a happy side-effect. Keeping cache data warm and available during network partitions is a largely solved problem; we have prefetch/hammer, we have serve-stale. (Also apparently we have whatever generates all that zombie DNS traffic Geoff discovered back in 2016, but I'd rather avoid perpetuating that mistake, which seems *quite* perpetual enough as it is.) Keeping cache data coherent is less solved: we don't have the trusted invalidation piece you mentioned. I agree that might be a useful line of inquiry. I guess that's the point you were trying to make; I didn't get it immediately because you started off discussing the shortcomings of an RFC that doesn't seem particularly directly related. So let's get specific about the problem and discuss requirements for a solution. -- Evan Hunt -- each@isc.org Internet Systems Consortium, Inc.
