It's worth noting that redundant networking gear and redundant power are the norm even in normal data centers. Having an entire row of racks go offline because of a router failure is already considered unacceptable and well-mitigated. Their biggest point of failure is probably the land connection. Looks like it's one big cable bundle. Those get damaged all the time from sea life, fishing, people throwing anchors where they shouldn't etc. Land-based datacenters have the same issue with excavators damaging power or network lines, but it's easy to run multiple lines far apart from each other when you are on land.
