This came during a CI/nodepool outage, OpenStack thought there were over 32,000 servers in the contint cloud project when there were, at the time, less than 10.
Quoting from IRC:
<chasemp> | Servers | 32536 | <chasemp> that's how many servers it thinks are in that project <chasemp> I see 7 in reality <chasemp> that's far more than total instances, that's more like all instances ever created by nodepool since x or something
