Undersea Cable Break Disrupts Life In Northern Mariana Islands 102
An anonymous reader writes: The Commonwealth of the Northern Mariana Islands experienced a devastating undersea cable break on Wednesday, with phone, Internet, SMS, banking services, the National Weather Service office, and airliners all being affected. The US territory depends on a single undersea fiber optic connection with Guam for its connectivity to the outside world (except for a backup microwave link, which was itself damaged during a recent storm). While services are in the process of being restored, this may be a prime example of the need for reliable backup systems in our "always connected" mindset.

No one is behind this. There was a typhoon and then a series of storms.
To put this into perspective there are around 50k people living on the island and its link runs through difficult terrain. It is about 100km from Guam itself hence why it could use a microwave backup. Honestly this is about as surprising as a small country town getting cut off by a back hoe hitting their cable.

Have a look at the coast around these islands. The coast is shallow and has a large amount of reefs. Surface storms of any size WILL impact things on the sea bed at that depth. Not to mention that the cables have to cross the shore at some point meaning they will be in very shallow water at each end.

What, they just have the things draped across the beach? I would have thought they'd bury it once it got somewhat close to shore...
Re: (Score:2)
Usually a channel is dug and the cable is laid in a conduit for the beach crossing. But that only goes a certain distance out and it is about the most expensive part of the cable lay. Even assuming they trenched 100m out that could easily be less than 4m of water over the cable and well inside the depth that a large storm would influence.

100 km is about 60 miles as I recall. I did not realize that wifi could go that far within the specs of the access points being made.

For a single hop 100km line-of-sight radio path that just skims the sea in the middle of the path, the antennas would have to be 150m tall on both ends (or some combination of appropriate heights). Those are mighty tall towers, which might explain the storm damage. If you want to clear 80% of the 1st Fresnel zone [proxim.com], you'd need an additional 33m at the middle of the path.

These islands are very strategically important to the naval control of the Pacific Ocean. There is a reason that the US has military bases there. There is also a reason that the Japanese took these islands by force during WWII. There are reasons to knock out communication on these islands, but they all involve conventional warfare with the hope that disruption to normal communication and air traffic would prevent the US from being able to prevent a change in the status quo in the Western Pacific.

FWIW, the Japanese did not take the northern Marianas in WWII. They did take Guam, but started with the rest of the Marianas under League of Nations mandate.
In WWII, they were strategically significant as part of the Japanese last-ditch perimeter, which is why the USN defeated the Japanese Navy soundly in the Battle of the Philippine Sea.

This were two seemingly unrelated events that independently took out two links. You can add links ad infinito but where do you end? Having two links sounds reasonable to me.

Your point about putting all the back ups in one place is a good one.
This is why backup procedures are to have the back ups be in different places.
Generally you want THREE redundant systems if you want a system that does not drop. And you want each of those systems to be in different places and possibly of different natures.
That all three will get knocked out at the same time is unlikely.
