Grantmcwilliams.com com was down for the last day because of a Gb-E network switch that decided to stop passing any traffic without any warning at all. It was probably find because someone hacked my Joomla template and inserted a greeting card submit form at the top of every page. An update to the latest Joomla 1.5.7 resolved that and taking the switch out of commision solved the other part.
Anyway, things are back to normal now.
