	I can ssh *into* sage/ns1 from any of my 10/8 servers immediately.
	However, on sage trying "% ssh tao" takes two minutes.  
	Something times-out.  Also, on sage.thought.org, I can ping
	anywhere.  On my internal servers, no; nothing reaches the 
	outside world.

	Hm, strange: dig ns1.thought.org worked yesterday.  Now, none
	of my secondaries respond.  According to my logs, something
	happened just before 01:00today.  My secondaries are at
	telstra.net and secondary.com.  I use dnsreport.com to tell 
	me if things are right.   They see what dig does... .


	Same with dig and the IP's in my resolv.conf.  dig is wedged.
	I've only rebooted past hour, tho. ....
