Frenquently disconnected from the caves server

Approximatively since the "hostile takeover" intermission patch (on July 31th), the caves in my game frequently been disconnected.

When I'm in the outside world, it's not a big issue, because it only close the caves entrances.

But it's very annoying while in the caves.

Could you quickly see what's up ?

I don't think I've made something special in the caves.
