Although when the technical webcast went black just at the moment when I'd expect the vehicle to come into sight, I was sure that something had gone wrong and they'd pulled the plug.
In the hosted webcast they explained that the droneship is on a satellite link and expected to loose connection as soon as the first stage closes in due to vibrations. Edit: someone else here said the exhaust fumes might also disrupt the satellite link.
...one day I'm hoping they'll release all the cut footage from the, um, learning experiences of the early Falcon 1 and 9. I'm sure that they've cleaned up the broken frames and there'll be lots of fascinating fireworks.
