With my explosives idea, I think (guess, really) that the lower bound is a speedboat. If they have a larger boat then that works too.

On the other hand, the upper bound is something large enough to be noticed. Records are kept of the movements of large ships, so you can't use something that large except as a diversion.

An anchor is blamed for one of the cuts:

Re Hack saw theory. Like to see someone hack through an undersea cable with a hack saw. Shocking thought.....

The joke is that the whole World Wide Net idea, its basic premise, was for a net with multiple redundancy so that it would be resistant to damaged connections. It would seem that the entire connection between India and Europe does through this one (or two) cables off Port Said.

The cost of laying the cables, manufacturing the cables and maintaining them is very high. There is only so much redundancy that they can afford.

Are there no connections over land?

Sure they are. But where land ends and ocean begins... Well.... You can't go overland anymore.

But mideast is connected to Europe though this little thing Asia and Africa, I can see cutting the cables to Australia as a problem, to the Australians.
The system is probably redundant because the region tends to be unstable politically so it is good thing to have multiple connections and under sea makes them hard to cut. The fourth one was actually turned off not cut.

Fun typo from the article...

As the world's fleet of $28 multimillion cable repair ships works to maintain the crisscrossing communications spider web, Beckert said more capacity is needed in the Persian Gulf to satisfy increasing numbers of Internet users.
Millions of toy ships?

Investigation ongoing:

February 18, 2008
...could have been an act of sabotage, the International Telecommunication Union has said...the cut to the Falcon cable between the United Arab Emirates and Oman was caused by a ship's anchor. But mystery shrouds what caused another four reported cuts...The Falcon cable has since been repaired, along with the Flag Europe Asia (FEA) cable which was damaged off Egypt's Mediterranean coast. The status of the remaining cable is still unclear.

I knew it!

OK, I didn't, but it did seem suspicious to me from the beginning.

The mid atlantic ridge spreads at about the rate your fingernails grow, so a relatively few feet of slack would meet that need for a long time.

How many were cut after? At least five according to some reports? Or was it less all along?

I wasn't worried about the change in distance, but more about the volcanic activity going on at the mid atlantic ridge. I assume there are places that don't have this lava activity and hence allow for a safe passage of cables?
