[PAR] Hypervisor network unreachability

An hypervisor had its internal network unreachable between 15:16 and 15:20 UTC. During that time, services on the hypervisors may have suffered a total loss of network connectivity. Applications have been redeployed because of the unreachability. The issue has been fixed and we are monitoring the situation.

EDIT 15:49 UTC: All services are now reachable again, the incident is now over.
