[Trac] www.clearsilver.net out of commission?

[Joe]

Hi,

I'm trying to install all the Trac prerequisites Trac on Windows XP.  I've got 
everything except for Clearsilver.  I visited their website last week, but since 
last night Firefox says "www.clearsilver could not be found" and ping says "no 
such host".  I also tried from the office and got a similar result.  Does anyone 
know if this is just a temporary problem?  Also, is there an alternate site for 
downloading it?
