Coronal mass ejection detection and mitigation if Earth's magnetosphere fails

An article on the disruptive power of a Coronal Mass Ejection and the aftermath on Earth if it slips past our magnetic field defense:

Yup. One consequence is a required full blackstart for the electric grid - after the shower is over. The last bad one, a direct X-level CME, was was in 1859. Nee the Carrington Event:

GPS and comsat would take a major hit.

We should invest in the Pony Express.

Some years ago I read that power companies keep only a few replacement transformers like the ones in the substations and that it took about six months to deliver a new transformer. I do not know if that is still true.

Here’s how to keep your own stuff safe maybe…

Given the current supply chain issues, I imagine there will be major problems in getting things back up Especially with the recent developments with China and the rest of the world.

Are there any other facilities besides the Inouye observatory capable of early detection of CMEs? If not is there thus a 12 hour period when it cannot detect CME activity? If true the 18 hrs warning drops to 6 hours.
I seems to me that loosing a substantial part of the grid for more that a few days amount of time will result in a situation that most people are ill prepared to deal with.
