6 days ago, a "pip install" step started to fail consistently on our CI jobs.
The last successful job is here:
https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/buil...
The first failed job is here:
https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/buil...

I've highlighted the diff between the two jobs here:
https://gist.github.com/pitrou/c88ff6245f02c062b292fea56299ecde

However, the exact same "pip install" step succeeds on my GitHub fork of the original repo (without any modifications!):
https://ci.appveyor.com/project/pitrou/arrow/builds/39334059/job/by...

Also, this seems to happen on the "Visual Studio 2015" build image, but not in another job that uses the "Visual Studio 2017" build image...

Did something change on some build images around 6 days ago?

    No changes have been made to both Visual Studio 2015 and Visual Studio 2017 images recently. It could be some external dependencies that are pulled during the build.

    Hmm, thanks for the information. Weirdly, as you can see from the logs, almost nothing changed visibly between those two builds...
