If your net is cable and your having issues, the explosion might have been a power transformer (they make a surprisingly big bang)
Nah, DSL2. I think the internet was just a coincidence. As for a transformer, dunno. My cabin shook and the sound came from atleast 2km away, my stepdad's house about another 3km away from me shook too and they're not even on a concrete slab.
Never seen one blow, but I don't know that there'd be that much of a shockwave.
Maybe someone finally figured out that woy woy really is the ass end of the world and nuked it from orbit... its the only way to be sure.
TBH, I'd be happy for them to do it. Place is full of animals, zombies, drugged up crazies and then the rest of us that dare not go outside.
