note that gzip/bzip/tar/cpio file test appear earlier in /usr/share/file/magic than the tests for html files

not to mention networks where using an alternate DNS server isn't allowed by policy (and/or filtering). I don't think it's unreasonable to use a 'known good' server for a test of some sort, but would disagree with overriding local configuration.

meh. anycasted instances of "global" dns servers like Google/OpenDNS provides are often better/closer/faster than the ones provided by an individual's ISP.
