iPhone 8 iOS 11 (Dulles, VA) queue not moving

There are 20+ pending tests on that test location / browser (Dulles, VA, iPhone 8 iOS 11) that hasn’t moved for several hours.

I’m seeing ~14 tests and the agent last picked up work less than a minute ago: https://www.webpagetest.org/getLocations.php?f=html

Could be there was a really slow test in the queue (9 runs, first and repeat view can take quite a while) but nothing looks wrong with the agent itself.
