All Delta flights grounded due to system-wide computer failure
Thousands of Delta Air Lines passengers around the world are facing delays with all of the company's departing flights having been grounded over a system-wide computer failure. (www.independent.co.uk) 更多...Sort type: [Top] [Newest]
Politics eh, well I guess religion could in future play a role too! Most issues the mere traveller has no control over anyhow - part of life some say but is it quite all that way.
I surmised that there was an excessive amount of reports of light chop was the reason why DAL was grounded.
Maybe Delta should look into Motor-Generator technology to isolate electrical loads from the electrical power supply line. This technology has been around for a very long time now; with it computers don't see any power grid hits, in fact the power grid could go off-line and the computer center would never know it unless someone from maintenance call to report the Gen's are operational.
It's a good general suggestion. Although motor-generator set-ups can be pretty expensive to build, it does work quite well.
Unfortunately, it's not perfect because it doesn't prevent all possible faults. The underlying issue is that recovering from a disaster takes continual practice, and anyone who's worked on highly available systems has seen some really bizarre failure modes.

You are correct, it takes constant practice and a operations protocol for exercising backup MG's. The expense doesn't end with the initial equipment purchase, maintenance personnel would require factory training on both the MG's and the switching equipment. The up side is clean power that you control rather than the power controlling you.
First world problems. Wilburrrrrr what have you created?
