Re: "no redundancy in the internet link"
So Gatwick generates the raw departures/arrivals data, posts that data to somebody else’s computer, then the screens pull that back to Gatwick. And it only uses 3 megabits...
So 2 questions:
0. Did they really need Somebody Else’s Computer to do this (especially if the computers that run this are still there, but now offsite - out of sight out of mind?)
1. 3 megabits... cut fibre... nobody thought of setting their mobile phone into WiFi hotspot mode - or dare I say it, backup 3/4G router ? Or is mobile internet that crap there?
