This user does seem to be using Wireguard, Yossi pointed out: #2934

Tom did some looking and suspected the Wireguard CI failover/restart issue might be related to KIND version bump, not a code change on our side. Aswin says maybe some IP routes or other resources are going missing during restarts.

Maybe should add a KI that 0.18 doesn't work perfectly with Wireguard+OVNKubernetes: https://submariner.io/operations/known-issues/

Aswin did some testing with OpenShiftSDN and also saw this issue.
