BA and it's IT systems problems
 

I got to wondering how such a giant in the aircraft industry could have so many problems: http://www.reuters.com/article/us-br...-idUSKBN18P01O

Then I got to the bottom of the article ... other giants should be aware.

Plus BA started charging for snacks :yep:

Running Windows 10, too much info going back to Microsoft caused a crash. :roll:

BA chief executive Alex Cruz says he will not resign and that flight disruption had nothing to do with cutting costs.

So? Power surge. What has that to do with Win 10?

I take it inviting workers to England and pay them better was out of the question.

Shut down could also be related to the recent religious fervor.

I have worked in IT outsourcing and offshoring since 2009 and moving IT to India is in itself not a problem anymore than it is moving it to any other country. Our IT service quality and customer satisfaction rose with the move...

We can only speculate into if that move made any impact.

No, what I wonder about is the power surge problem. Any serious business with a 24/7 availability requirement must build critical IT systems with redundans.
That means spreading production systems over more than one datacenter and with different powersources and hooking up to separate powergrids.

If power was indeed the problem, then BA has a MUCH bigger and fundamental IT design problem...offshoring is insignificant in that perspective.

Well put matey :yep:

One must account for the slim possiblity that redundant power sources went out at the same time because even with extensive redundancies you dont get 100 percent availiability.

Very doubtfull, as the consequence would have been that both datacenters connected powergrids would have failed. Datacenters have redudancy by connecting to 2 powergrids (at least), so min. 4 powergrids that have homes, other businesses etc would have been down. If that was the case I think it would have made major news :)

Datacenters and high availability systems have redundans built-in on many levels. Its not very uncommon that redundans is activated on storage, network or other levels. It takes a disastor to impact power on datacenters to the point where both fails.

Back in the day when I was involved in Disastor tests we joked with the scenario of both datacenters failing, because if that was the case pur country would be in a disastor situation :)

You would be a good man to have on anyones think tank boardroom, Mc Beck :up:

If you know the location of anyones power source and back up power source ... then all you would need is a sleeper cell or two with those new hand held EMP guns to disrupt your enemy, right?

The future of warfare just gets more compilcated.:hmmm:

Well, we also joked about the actual fact, that if you really wanted to perform an attack that impact a country, target whole datacenters that act as eachothers failover. Chances are that this could actually cripple/kill companies and even impact whole countries. Just think taking out datacenters that hosts top 2 banks in a country + a few central big business.

Look at it from another direction - 99.9 percent availiable datacenter would still be unavailiable 1 day per 3 years. Despite how improbable it may seem that a datacenter would fail, especially to a specific cause (power), between the many datacenters it would occur fairly regularly.

p.s. my view is formed by operations of a major telecom and other services provider.

This is all right and perfect, but as McBeck and Ikalugin say, a 100 percent security is almost impossible to reach, and pay for.
You get 99 percent ok, but to have 99,9 percent the costs already rise exponentially from 99. Failover clusters are all nice unless you have a real big and lasting power cut.
I take it that BA's server farms are distributed all over the UK, and also abroad. But if the ethernet connection fails (routers need electrical current, too), it does not work at places where the power fail happens.

Also the data synchonizing is a real headache already when all works, with Windows. Even if branch cache and failover clusters work perfectly, power backups like Diesels only work locally and temporarily, and will not support all the routers between e.g. London and Liverpool.

The urge to control all digitally makes us very vulnerable, apart from also giving up personal privacy. Marc Elsberg describes that very well in bis book "Blackout".
