David, Thank you for your answer ! This log entry arrived just after (and is certainly due to the fact that) I closed network communication between srv2-1 and srv2-2 : I connected to secondary server and used iptables to stop communication between the two servers. Just after that, primary server was reachable again ! But according to logs, issue started 2 days before. However, to answer your question, the network between the 2 servers is the private dedicated network OVH uses between its 2 data-centers RBX & SGB : http://www.ovh.co.uk/dedicated_servers/data_centre_selection.xml I have a 100Mbps connection between the 2 servers.
