Conda and Slow Proxies

The default conda connect timeout is 9.15 seconds (no idea why this is, seems to have been the case from day one). If the proxy is slow, e.g. it is in another country or AWS region, this timeout can be triggered and conda will prematurely close the connection.

To diagnose this issue, attempt 

curl https://repo.anaconda.com/pkgs/main/linux-64/current_repodata.json

with proxies enabled. If that works then increase the connect timeout as follows

conda config --set remote_connect_timeout_secs 30

conda should now be able to update and install new packages etc.
