hmm... it seems that's because the repository is down, so now we're falling back to the PyPI version. @tacaswell, can you confirm?

It does look like the rackspace server we were pushing to seems to be down. This is more of a @matthew-brett question.

Thanks @tacaswell :) Er - sorry - I'm lost - is the problem that xarray can't see the Matplotlib --pre binaries?

yes, we can't seem to use pip to install the pre binaries using

python -m pip install \
        -f https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcdn.com \
        --no-deps \
        --pre \
        --upgrade \
        matplotlib

also, when pointing my browser to that url, I get a resource not found page. I'm not sure if I did something different back then, but I think when I last did that about a month ago I got a page listing the available files instead.

Yup - sorry - those URLs went down a while ago, as Tom said. Tom - are you uploading --pre binaries to Anaconda or similar?

if not, it might be worth copying numpy, pandas and sklearn which upload to https://pypi.anaconda.org/scipy-wheels-nightly/

Can you point me at the configs that upload to the correct place?

I don't know how those projects upload to that repository. @TomAugspurger, can you help with that?

Edit: https://github.com/MacPython/pandas-wheels/blob/master/azure/posix.yml, maybe?

Yep. I believe that @ogrisel can add you to the organization on anaconda.org so that you can create a key to upload to packages.
