Downtime

Sat nav users could find themselves up several creeks without a paddle soon because it seems the satellite network that makes it all happen, could be falling to pieces.

US officials say the 20-year-old global positioning satellite (GPS)network is in dire need of repairs and upgrades.

Let's hope that the GPS network is too important for the US to allow to fail, because otherwise lots of people will be in hot water.

The UK's predilection for roundabout every few miles and even yards, is likely to result in millions of people going in circles with no sat navs telling them when to exit.
