This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
The trick to high availability - #keepcalm
If a plane's engines were to fail in flight then because most of them
have two, the pilot the lands the airplane. Mostly its only one engine
and rarely two as what happened with "The Miracle on the Hudson."
When the plane lands the aviation engineers then replace the failed
component, test its operation and integration and the plane takes back
to the skies. They do not do an inflight engine swap out at 10000 ft.
However, network engineers seem to always try the latter with
spectacular adverse major incidents.
