Just checked, it's still there and functional.
We don't have a web frontend for code browsing through -- it's just a repo and nothing more. So you can't open it in a web browser, but you can clone it with a git client.
git clone
http://repo.cohtitan.com/icon/icon.git(or the equivalent with whatever client you're using)
I may create a github repo for it at some point for easier browsing, when I get a spare moment.
