According to http://shinken.wmflabs.org/problems the following hosts are unreachable and down:
- deployment-puppetdb01: deployment-puppetdb01 is DOWN since 2M 3w 5d 22h 7m 2s
deployment-tmh01: deployment-tmh01 is DOWN since 1M 3w 2h 7m 29sdeployment-videoscaler01: deployment-videoscaler01 is DOWN since 1M 3w 2h 7m 44s
all of them have the "no route to host" flag.
Thanks
