Is that the Ada code base?
Half of European flights delayed due to system failure

Re: Half of European flights delayed due to system failure
#12I was on a plane just about to push back at Heathrow, and the pilot informed us we'd be delayed 15 minutes due to this failure. In the end it was 10 minutes, and we landed only 5 minutes late at my destination. Doesn't appear to have been a big deal, at least for me.

#13For those curious, Eurocontrol MUAC (Maastricht Upper Area Control Center) migrated to 50 virtual SUSE Linux Enterprise servers running under IBM z/VM hypervisor on a IBM z196 mainframe system in 2013.

Well the archaic systems are getting older and older. From what I've heard it's almost impossible to get replacement parts for some of the computer systems that run airports/airlines.
And on the other hand, there are massive requirements at all levels for this kind of software. I'm not sure what the right answer is at that point. From dev-experience, I wouldn't want half-assed software directing flights. From ops-experience, I don't want software directing flights requiring specific hardware so you can just replace the hardware with easily available hardware.
From dev-experience I would be surprised if SpaceX rockets run with decades old assembler code-base.
I still believe we can create bug-free solution with modern toolset. It's a matter of zeros behind the project funding.

Why? Sure, the skies are more and more crowded, meaning more and more people will be affected by a once-in-20 year failure, but why would it happen more and more common?

Not sure about aviation, but in other industries they virtualize the old hardware on a new architecture, and keep the software going.

#16In situations like this I’m glad I book my flights with Chase Sapphire Reserve. It comes with a trip delay reimbursement for up to $500 per ticket if a flight is delayed more than 6 hours. No sweat!

Does any of this effect the nature of the failure? Have they said what went wrong?

#18> Eurocontrol announced the system restart later in the day, after what it called extensive testing. So they turned it off and on again.
Bastards.

That's a good point. I'm just a bit disillusioned with the quality of some of the legacy stuff at my current place. Especially because robustness and probability of failures is mostly determined by requirements.

anywhere we can read up on this? :)
