Network solutions DNS failure

I couldn't bring up this web site in a browser, but httpd's were running and an ssh session on my desktop for several days was still up. Four possibilities, in order of awfulness:

1) Someone hacked my machine and repurposed it to send spam or launch DoS attacks (it's happened before, but not in the last two years, despite my never upgrading the Linux version I'm running)

2) LLIC configuration changed somehow, must consult with Steve (awful only because Steve always ends up asking me questions about my configuration that I can't answer, then summarizes my cluelessness by asking me why I'm "not running Debian," in the same manner a person might ask why a child insists on wearing his shoes backwards...)

3) SBC messing with firewalls or other strange configurations

4) Temporary netsol DNS trouble

Thankfully, it was the last possibility:
