Fiberglass is often very easy to find here in Belgium. In various places you have “las pits” that are fairly easy to reach. They look like rectangular sewer covers with even the name of Proximus or Telenet cast in them.
Sometimes these are also shared with other providers when they follow the same path and there is a collaboration between them (think of a Fluvius and the like).
You only have to open such a lid and with your bolt cutters you can cut through different fibers.
That will not immediately be the fibers of “the internet”, but you do enough damage with it to shut down the average industrial estate, large company, … for several hours to days.
Here in Belgium too, there is a lot of fiber optic along just about every railway line. Formerly built by Syntigo and now bought by Eurofiber. That is also nice in those concrete gutters. Again, just go through that with your bolt cutters and you’re done. Certainly the connections between the larger cities run through there.
All very easily accessible. Partly logical because in these times, with the great growth of fiber optics, you do not want to dig open 500 m of pavement every time you want to connect a building to (dark) fiber. You just make welding pits every 100 meters.
