Unless, of course, you meant five nines of downtime. (For those of you who don’t know what this means, check Wikipedia here).
It appears our hosting server has had some issues lately, causing an abnormal number of reboots, and Dustin’s auto startup script for our stuff isn’t working anymore. Combine this with the fact that we don’t know the site is down unless we visit it ourselves (which you can tell from my posting history happens rarely at best), and you get random long outages.
We’re working on it and hopefully the site will stay up for more than five minutes in the future. Maybe.
