Even at 1000 bytes, we're talking about 40GB for the entirety of 
California. You can get off the shelf cloud VM's with that easily these 
days, and 10 of those covers the US (ok, redundancy, but still...). 
That's probably why DoH wasn't a big deal. Throwing memory at a problem 
these days is probably easier than any heroic measures.
