We were not seeing failures before this time, and we have made no changes to the code.

What I see is the current job is failing on {{Downloading pyarrow-5.0.0.tar.gz (739 kB)}} while the successful ones did {{Downloading pyarrow-5.0.0-cp39-cp39-manylinux2014_x86_64.whl (23.7 MB)}}

{{Thank you for your help on this!}}
