During running a command %run prep.py -d flights in 01_dask.delayed.ipynb.

I receive URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:847)>

Does that fail on a binder session launched from https://tutorial.dask.org/01_dask.delayed.html, or just your local machine?

Just wanted to follow up here, @nialeksandrov does the data download fail on a binder session or on your local machine?

%run prep.py -d flights --no-ssl-verify

I'm running into a URL open error when I try to download the flight data from binder.

URLError: <urlopen error [Errno -3] Temporary failure in name resolution>

Since it says "temporary failure", I would be tempted to wait and try again later
