Many researchers have told me that my site is not available in China. According to the company that is hosting my DNS entry, this is due to a Chinese access restrictions. To work around this problem, simply use the URL http://www.cs.cornell.edu/People/tj/svm_light/ to enter the website. From this url, you can also navigate to SVM-struct, SVM-perf, and all my other software. When you want to download some file, replace "download.joachims.org" with "osmot.cs.cornell.edu" in the URL. So, for example, http://download.joachims.org/svm_light/current/svm_light.tar.gz becomes http://osmot.cs.cornell.edu/svm_light/current/svm_light.tar.gz I hope this solves the problem.
