issues with tserv1.lon2 and tserv5.lon1?

[jordipalet]

Since Friday night two different tunnels, using 2 different GPON links, one to tserv1.lon2 and the other to tserv5.lon1, every few minutes get dropped.

Nothing changed in our side, and IPv4 connectivity is stable.

Nothing seems to be reported in the tunnel server status, so not sure if someone else is noticing the same trouble?
