Doomsday and the DNS resolution
Last month I did a short webinar with Indian ISPs talking about DNS servers in detail. The idea of the session was to make network engineers from fellow ISPs familiar with root DNS servers, DNS hierarchy, anycast etc. As we went through slides it was clear from RIPE Atlas data that Indian networks are not reaching local DNS servers due to routing! (Data from RIPE Atlas here).
This may come as a surprise for policymakers (where there seem to be ongoing discussions around how India can have its own root DNS servers even though) we are not hitting existing local root DNS instances.
