Where's the actionable information? A bump up in a graph doesn't report anything. At best, there's retrodictive curve-fitting going on. Still, perhaps worth pursuing as a matter of theoretical interest...
Star Wars ping. They detected a disturbance in the Force. Hopefully, they won't go over to the Dark Side.
But when numerous graphs around the world bump up in synchronization, whose correlations are normally near zero, there is something going on. If these were seismographs the answer would be obvious. If there were a built-in artifact in the electronics (like a common random number seed) that caused a synchronization at a later time it would be easy to understand. But as far as anyone knows, no prosaic explanation covers this phenomenon. I agree it is worth pursuing and would be negligent not to...
