Hey British Airways, Here’s Five Whys It Was Not The IT Person’s Fault!

British Airways has not released the official post-mortem or details yet, but a friend did find this interesting article which I had not yet read when I wrote this.

While a decades old UPS is actually the thing that failed (and should have been replaced), as I outlined in my original argument that was probably a separate thread in analysis.

What is still interesting is why the outage lasted days instead of hours. How quickly was power restored versus how long it took to get the system working? We lose power to datacenters, UPSes fail all the time. It has been one constant in my IT career :)

Like what you read? Give sumbrymatic a round of applause.

From a quick cheer to a standing ovation, clap to show how much you enjoyed this story.
