forwarding rvm/rvm#2743 (comment): parsing s3 index is quite slow and is limited, can you provide index.txt with list of all files, for example see http://binaries.rubini.us/index.txt, it would be best if http://jruby.org.s3.amazonaws.com/index.txt would contain list of files in http://jruby.org.s3.amazonaws.com/downloads, but all the files are ok too.
