It's up right now for me. Yesterday (?) when I finally just posted the link to the Kago story from H!O at JPM, I noticed that H!O was down, though. Maybe they're having a bit of selective instability as well?
Turns out that for some reason my browser is not resolving the site. I recently upgraded to FF3.1b1 so maybe it doesn't like the javascript on that website. Odd because I'm not having any problems on any other sites. But even so, I'm able to get through with Internet Exploder, so no worries mate!
