Hey Skritter team,
First major bug/downtime that I have encountered... for about the last ~3 days I haven't been able to use Skritter at all... if I go to the practice page I get anything from "the server is not responding" error page to an almost loaded app with some or all of the buttons beneath the character drawing area missing, one time I was even able to write a couple characters without the buttons but I gave up after a couple.
I tried on Firefox 3 and 3.5(beta), and my guess is it is something to do with the fact that I am inside of the PRC. Let me know if you need more info, and I will try on another computer and internet connection sometime to try to reproduce.
Peace.
