Twent years ago...
I remember designing network infrastructures on behalf of BAA some 20 years ago (1996 - 2000). Three of them were in the UK, the others in far flung places. Back then all network infrastructures had to be designed to survive catastrophic failure e.g. bomb blast, fire, flood, air crash etc., and be capable of "self-healing" - i.e. have the ability to continue processing passengers within 3 minutes. All the major airlines including BA insisted on these requirements. Not an easy task back then but we managed to get the infrastructure restore down to 30 seconds.
It seems like BA have sacrificed those standards in favour of saving money and that it now has a system which takes 3 days to restore. I wonder how much that will cost them?
Progress.
