I know how to setup my own DNS server with manual entries and caching, but is it possible to mirror/copy one (or multiple) of the major providers like google to ensure you have most of the internet covered automatically?
It is probably far more feasible to set up your own DNS server as a caching server, and manually set the cache expiration time on records to be max limit (which I think is 30 days for linux servers like BIND). Then just surf like normal so the cache builds up records.
In a case where the internet has gone down globally for any length of time, we'll probably have more important things to worry about if it's not back functioning normally within a few days.
