[sf-lug] Notice: ns1.svlug.org downtime, DNS secondary

[Al]

I don't think I'm directly affected by svlug being down since I don't 
AXFR from ns1.svlug, and I don't originate any records that define svlug 
to be a domain server, but good to know what's going on.

I wasn't monitoring ping status for svlug but I've added it to the 
list.  Historically I monitor balug and linuxmafia.  (linuxmafia stays 
up just all the time! :) )

I check BIND status every 10 minutes but haven't seen any transfers 
hung, because of course I'm not transferring from svlug.
On my 10 minute checks I haven't been comparing the contents looking for 
change in zones I was seconding but, since that's a normal function I do 
for internal zones, it was easy to add that; because I hadn't been 
checking I didn't see the list of name servers change. Next time I will.
