Apparently over the night the firewall which controls access to lop1 
became
inaccessible which triggered automatic failover to

;; ANSWER SECTION:
lock.autonlab.org.      300     IN      CNAME   webfwd1.zoneedit.com.
webfwd1.zoneedit.com.   300     IN      A       198.199.92.59
webfwd1.zoneedit.com.   300     IN      A       162.243.226.87

note Zoneedit (now the part of EasyDNS) is our DNS provider. There is 
nothing
wrong with lock and lop1. I can log into them with my regular 
credentials from
interior machines. You can't because you are actually hitting EasyDNS 
servers.
I have to restore proper DNS records. Give me few minutes.

Best,

P.S. I noticed that sometimes our public static IP addresses become 
unavailable
but I have not being able quite to point to exact source of the problem. 
There are two
suspects. CMU or CMU's Internet service provider (I forgot the name of 
the name of
the company but it is a government/business provider only). CMU also has 
few misconfigured
authoritative DNS serves located in New York which I reported but they 
never did anything
about it.
