Delta Airlines’ Power Hit Fiasco Proves That Today’s Corporations Sacrificing Mission Criticality For Profit.

From the BBC reporting on today’s “6-hour” meltdown. Google for much, much more.

That all of Delta’s systems went down — for at least 6 hours — when their main datacenter in Atlanta, Georgia, got hit by lightning is LUDICROUS.

Since the advent of high-speed, high-capacity optical fiber-based networks in the 1990s we have had the technology, expertise and experience to implement ‘mission-critical’, ‘zero-downtime’, ‘disaster recovery’, mirrored data centers to avoid exactly this type of meltdown.

My speciality in those days, when I was “Mr. SNA” for over 20 years, were these so called ‘Mission Critical’ networks. Systems/Networks that could NOT be down for much more than a FEW MINUTES since such an outage would adversely impact the business mission of an enterprise. This was particularly true for airlines, banks, financial institutes.

That Delta does not have a mirrored data center operation is SAD but telling.

Mirrored, disaster recovery data center operations are HUGELY expensive. No question about that.

So Delta like so many other corporations of today are forgoing ‘mission criticality’ in the interest of profits.

Basically Delta is saying that they are WILLING to take this type of hit, every few years, rather than spend tens of millions of dollars more, EACH YEAR, on maintaining mirrored data centers.

I just wanted YOU to know that this Delta fiasco was eminently avoidable.

Do YOU Know YOUR Planes? Fun Airliner Identification Quiz.

Airplanes is yet another of my very long list of interests, albeit one fairly high up on that list. I was going to be an aeronautical engineer before I was told, in 1969, that there were this new fangled things called ‘computers‘ that were the wave of the future. Plus, I have spent a fair amount of my life on planes. During 1985 & 1986, I must have spent 35% of my life on planes since I was in the top 2% of frequent fliers on both American and United. During 1992 to 1999, I must have spent 20% of my life on planes. I used to know my planes real, real well. These days, at most, we fly once a year. But, I still look up in the sky, like a little boy, when I hear a plane.

So when I saw this quiz I wasn’t sure how well I would do. I was amazed. I got 90%; just one wrong in the 10 I was asked to identify. I call that residual knowledge, stuff that your brain absorbs and holds on in the hope that it might someday be useful.

If you like planes or spend a lot of time in them try the quiz. It is fun. Also lets you appreciate how similar Boeing and Airbus designs are; now acknowledged as proof of how form always has to follow function.
