If anyone contacts you now and offers to loan you an excavator, be suspicious.

This was my thought as well. Plus this particular dc is massive and would require an absurd amount of c4 to destroy.

Or drive by with an overpowered RF amp and signal generator (sdr). It would brick a percentage of the network equipment and not physically harm anyone. If you knew what equipment they had you could even research which frequencies/harmonics cause the most havoc to their gear.

Yep, you can do way more damage to a data center with a bulldozer than with a truck bomb, almost as fast too.

If you know where the fiber comes in, longer lasting damage.
