The undersea fiber cables that were cut a couple of months ago were the subject of numerous conspiracy theories, but satellite photos have revealed the culprits--cargo ships that were anchored in the wrong place. Sometimes Occam's Razor (the simplest explanation is the likeliest one) is exactly right.
The object lesson for communities is to plan for cable outages by making sure local networks have redundant cable paths. Sometimes this is quite expensive to do when just getting started with community telecom investments, so an alternative to a second fiber cable is a high capacity wireless link that can handle local traffic (perhaps with somewhat less throughput) while repairs are made.
