The government seems to be expecting something bad to happen in Easingwold, Leiston and Glasgow, as these are the three areas that'll be testing two new emergency alert systems for mobiles.
Around 50,000 people in the soon-to-be-disaster-struck zones will be testing the options in the next month or two, with alerts letting them know about floods, industrial accidents and more. The Cabinet Office is working with O2, Vodafone and EE at the moment, with the trial using two separate delivery methods to get the doom-laden messages across.
One will send people a standard SMS notification, the other uses a cell broadcast message that looks more like the notifications you occasionally receive from your mobile network. The latter seems to be the favourite option, as SMS messages are obviously much easier to fake and operator broadcasts aren't hindered by network congestion.
And when the aliens come, there's going to be quite a bit of network congestion what with all the photos being uploaded to Instagram. [BBC]
