Currently G isn't answering queries, so it's not causing a problem.

A.ROOT-SERVERS.NET and H.ROOT-SERVERS.NET don't agree as to the minimum
TTL (518400 vs 172800), but that's not going to wreck anything.

This is why BIND 8 has the bogus characteristic, or why one may need to
edit their root hint file.  Too bad both require a reload/restart.
