9 years ago, Mike wrote a legendary blog post called Problems' Materials Publishing, you can see it here. I found the blog post from http://codeforces.net/help.

The blog contains this awesome sentence:

later you will be able to download contest problem archives that will contain full texts (or their generators) as well as the authors' solutions and other materials.

As 3415 days have passed since the blog post, I thought I should be able to download those problem archives, but I cannot find them anywhere. Could anyone suggest how can I download problem archives?

Please think before you downvote.
