I have been using the Tor browser bundle.  However the website www.3quarksdaily.com fails to load... it returns "404 page not found."

The website loads perfectly fine outside Tor.  I wonder what the problem is?  (I saw a similar post on tor.stackexchange from last year but in that case the problem website was first presenting a captcha.  In this case there is no captcha, so perhaps the problem is different...)
