Details

This: https://aws.amazon.com/blogs/aws/amazon-ec2-update-streamlined-access-to-spot-capacity-smooth-price-changes-instance-hibernation/ started at about the same time as this week's provisioning issues (behind bug 1422295 and that led earlier to noticing bug 1421618): spot requests are failing for "price-too-low", which shouldn't happen if we're using "real" pricing data -- but I assume the "smoothed" pricing data is a marketing term for "fake" pricing data. We're also getting a lot of "capacity-overcommitted" (or something of the sort) which suggests to me that AWS is out of capacity. And that would make sense if reserved instance prices just dropped to spot prices -- everyone will pile in and use all of the available capacity. Anyway, eu-central-1 seemed to have the least capacity, and we removed it from a few workerTypes and saw them perform better.
