Everything down?!?

Hi-

name: csense
domain: http://colonialsense.com

Been getting 'server not responding' msgs for many hours; obviously not a widespread problem or there'd be other posts. The errors (on multiple devices) occur on:

http://colonialsense.com/Colonial/Main.php
https://hero.gigadnsserver.com:2083
http://www.status.gi9.co

Did something happen with DNS? Everything was fine, then everything just crapped out...:-(

Any clues appreciated...

Many thnx,

-CSense
