To get CI working, I marked four Windows hosts as offline. They were failing CI tests consistently.
- test-rackspace-win2008r2_vs2017-x64-1
- test-azure_msft-win10_vs2019-x64-4
- test-rackspace-win2012r2_vs2019-x64-2
- test-azure_msft-win2016_vs2017-x64-3
Not sure what the right thing to do to get them back online is.
