Apologies for the site outage the past 12 hours… Here is the explanation provided by my hosting company, site5.com:
It appears that the permissions to your web directory were modified and no longer gave permission to apache to enter the directory. I’ve changed the permissions and your site is back up now.
I love how hosting companies insist that their servers have a 99.9999% uptime… but little f*ck-ups like this don’t count, since only my site was affected, and the server was “up”.
Time to email the billing department…
