Hmm. Possible that it was down? What did "wget www.jython.org" do? It's working for me presently.

If it's still failing, feel free to substitute a different URL, that particular one isn't critical, just something to download. :)

wget gives me: Unable to establish SSL connection.

Strange that python io_threading.py work's correctly with python requests.

[jima80525]

I just checked and the threading version is using https as well. Perhaps requests is doing something smarter about SSL certs than aiohttp is. That seems the likely candidate.
