I feel like this is going to put me on a naughty list somewhere... 😮

Hey @DaveShuckerow,

I know this is annoying, but it looks like Cirrus got the hick-ups on this PR. It aborted all runs without properly reporting status back to github. I don't see a "re-run all" button on Cirrus anymore. Rather then restarting each shard individually, I believe the quickest way to re-run all tests would be for you to push a new (empty) commit. Any change you could do that?

Sorry for the inconvenience.
