I stopped and checked ART’s comm, but it was only picking up static. I didn’t think it was any deliberate attempt to block my connection to the rest of the installation; I’d experienced that type of outage before and this felt different. I think this tunnel was so deep below the surface that the comm and the feed needed powered relays to get out, and those weren’t functioning anymore. Something ahead still had power, because my feed was picking up intermittent signals, all automated warnings. I kept going.
