I remember in the late 90s/early 00s a lot of cases when sites would go down (everybody self-hosted) due to backhoe events and the like.
These companies weren't idiots: they had replication for their databases and leased redundant transmission service because they knew this kind of thing could happen. The problem is you'd buy transmission from two providers...whose fiber turned out to be in the same conduit, or even both had rented bandwidth on the same fiber.
At least people are smarter these days, and with widespread cloud service there are fewer people who need to keep track of this stuff.
