Midnight system screwup (and fix!)

Anurag Bhatia
I was just working (and playing music!) and realized that “Movie player” package given on default Ubuntu installation isn’t of much use. Decided to uninstall it, next needed arping for some test and installed it (via default debian repository). Something crazy happened here. I opened something on personal server and it gave DNS error. I shot couple of digs from terminal and all timed it. I was scared to hell thinking of DNS failure on personal domain which is very very unlikely since I am using multiple DNS providers and close to a dozen of servers serving DNS zone.
