We've been running at 10 max servers for a day and a half and there are
no errors launching nodes according to grafana. Additionally the mirror
node (http://mirror.us-west-1.packethost.openstack.org) is still up and
running.
I think we are good to bump back up to 100 max servers given this under
the assumption that the disk size increases have made things happier.
