[Dshield] Undersea cable cuts

There are still conspiracy theories, this time centered around the odds of there being a satellite that just HAPPENED to be photographing that area at the time...
This is a basic application of Bayesian statistics; we already have a pretty good idea of how often cable cuts occur (about once every 3 days) so we can calculate the odds that 5 cables would be cut in a 12-day period, globally (about 82%). I don't think the odds are much less when you factor in the "fortuitous" satellite imagery, or the close location of the cuts.
Even if you assume that there is a conspiracy, it means that from these data we can't tell a conspiracy from random events.
Of course, I am not a statistician so, grain of salt and all that.
I actually would like to do a more granular study of the cables and come up with a metric for the probability of X number of cuts in Y days in Z geographical limits. I'm pretty sure we could use that to establish a threshhold along the lines of "If so many cables servicing the UK are cut in so many days, then it might not be random." Anyone want to help with some research and data entry?

it looks like the Denials of Service in the Middle East as a result of
undersea cable cuts are at least partially explained by "rogue anchors".
Here is the url to the mention of that cause at the Engadget www site:

What are your thoughts on this from a security professional's standpoint?
