This site has a wealth of information on how to get around blocking software and the likes it also has an email service that will email you daily new proxy sites to check including all the new https:// ones also:

If that doesn't work, you can join our e-mail list where we mail out new Circumventor sites every 3 or 4 days. Of course, employees of blocking software companies have gotten on this list as well, so they add our sites to their blocked-site database as soon as we mail them out, but in most places it takes 3-4 days for the blocked-site list to be updated. So the latest one that we mail out, should usually still work.
