Comms Disruption Ahoy
And now, provide Alan Quaida and his mates have a few braincells between them, they'll see where the accident happened on the news, know that there is major infrastructure running by there and get the spades out and start digging.
Even if they don't tap the pipe, they can certainly cease the service.
NB - This is not an incitement to dig - don't do it - its very naughty. And no black helicopters please!
