Client Subnet does help the issue, but it doesn't actually fix it until support is near ubiquitous across intermediate nameservers that have clients in other geographic locations…
Well… that and any other DNS server that supports EDNS0 client subnet.
(I believe that the fact that Google found a need to create EDNS0 Client Subnet *at all* is proof that using the DNS address for localization is problematic…)
Sure, but anycast is even more problematic and those are basically the only two alternatives currently known for solving the problem in question.
And again - it's still something that needs work upstream to support, and you *still* have to deal with the case where the intermediate DNS server doesn't do Client Subnet.
Or accept that no solution is perfect, make this one as good as we can for now and move on.
I say slightly pessimistic because there aren’t all that many 3XX responses being reported.OK, that's a slightly different kettle of fish :) To the nearest 10% or so, how many are answering with a 3xx of any sort?
Well… I’ll post a separate message detailing my findings. It’s more interesting than I previously realized because none were reporting 3xx results and all 3xx results were getting hidden behind 5xx results which weren’t (all) entirely valid. Owen
