Why could external URLs be a problem? And is it still one if you swap https to hxxps or something? What could go wrong with having a URL as a comment in code?

I put URLs there sometimes and think it's very helpful.

You don't control these external resources, and now the explanation of what your code does is tied to a site that could be taken down tomorrow, leaving you with a dead link and an unexplainable regex.
