You know it. Before they turned off public feed, they probably installed new, updated and more sensitive buoys at ideal fixed station positions and labeled them something vague and innocuous. These quietly transmit to satellites and a private (no public feed) channel to warn them when Continuity Of Government protocols need to be activated. Add in high-altitude spy planes loitering around La Palma watching for the Event- as well as Human Assets on the ground reporting what they see and hear. Interestingly: I remember a while back someone supposedly leaked screenshots from a COG Test in the form of text messages informing the VIP recipients that had it been a real event, they would have an hour or so to rendezvous at a designated location. They looked pretty convincing.
