Title: What is the impulse response of the world?s economy?
Post by: evan_au on 23/07/2024 08:02:09

The recent Microsoft/Clodstrike outage gave a 1-day kick to the world?s economy.

It was felt immediately at airports and ATMs.

After a few days, it is showing up in empty supermarket shelves

I suspect that the flow-on effects will continue reverberating for weeks or perhaps months?

In electrical engineering terms, this is the impulse response of a system.

Will this measure the impulse response of the world economy?

My best guess is that it's like trying to measure the impulse  response of a tree.
Lots of mass spring systems with different resonance frequencies, and all heavily damped.

Apparently, Cloudstrike took down about1% of computers running Microsoft Windows, world-wide  (presumably, the others were either turned off at the time, or running some other brand of anti-virus software).

A lot of cloud servers run some form of LINUX, so presumably even less than 1% of cloud servers went down. 

A lesson in interconnectedness - a supply chain is only as strong as its weakest link!
