vdsm_master_network_functional_tests_gerrit job's host is down

Hello, please, could anyone somehow repair master_network_functional_tests_gerrit job's host network http://jenkins.ovirt.org/view/All/job/vdsm_master_network_functional_test... It's unreachable now and David Caro (who always helps me with this) is on his PTO. Do not try to restart it. `service network restart` could be enough. Thanks and best regards, Petr
