Earth is a single point of failure.
Telegeography has created a nice map showing the affected cables.

NTT reports it has fully restored all its circuits through other routes.
Other carriers in the region are reporting 80% to 95% of normal service
has been restored through other routes.
IP does not provide survivability UNLESS you have alternate, diverse
connectivity. But alternate routes are often more expensive, higher
latency, i.e. less competitive.
