Update:

        Escalated to provider
        ----

        Provider confirms fiber break. Measurements ongoing to
        locate fault location
        ----

      * 20220804 21:40 UTC
        Due to heavy thunderstorms no access to the fiber is
        allowed, it's colocated with power cables. When weather
        improves repair work can start.

        The troubleshooting will start soon. No ETR yet.

        Technicians have now made a measurement from one side of the
        connection and are working on the other side right now. They
        also discuss temporary solutions for how they can achieve a
        temporary solution to the problem so that the impact is as
        mild as possible.
