Comment 9 for bug 1812552

Seems to align with when this started spiking the failures in tempest-slow:

http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22in%20120%20sec%20and%20the%20ping%20result%20is%20unexpected%5C%22%20AND%20tags%3A%5C%22console%5C%22%20AND%20voting%3A1&from=7d

The special thing about the tempest-slow job is it runs 2 nodes and it runs slow tests so tests that don't normally get run in other jobs like tempest-full.
