Weird, I haven't researched DNS as well as I should have. I always lived under the impression that there was this extensive DNS cache network where intermediaries responded to queries with cached results from root DNS servers.
Instead, the second that this DDos hits is the second we have websites stopping working.
How is it that in this day and age we can't have distributed caches of DNS entries at our providers of full dns databases. I mean there can't be more than like a few billion dns entries in the world total, which fits easily in a modern desktop computers RAM.
If that is an underestimate, I can't believe a single modern server wouldn't be able to mirror the world's DNS queries for at least a providers worth of users.
