Power outages, floods, tornados, but everyone knows about that and corporate foulups.
I have yet to have anyone describe to me what will happen during the next Carrington Event.
Let's just ask the real & rational questions based on past history:
1. Will your laptop survive as plugged into the AC outlet & will there be any AC power?
2. Will your data connection remain "up"?
3. Will your "Cloud" & email systems & storage remain accessible?
4. Will some of your remote data be lost forever? I can answer that. "Yes", said Bo Regardless! (I am dead certain AWS and others will deny what I said by replying "But we have redundancy.")
So, what do I think about password managers? -- You better keep a rotating group of small SSD devices (& some paper backups of core items) in a locked steel sealed box that you keep rotating backups through that does not require a profit making 2nd &/or 3rd party to control which could go bankrupt after the data center goes poof. (Does LastPass even OWN its own ALL of its data centers?)
Worse yet! How many months or more will it take to get 50% of the services back up?
I'm not sure that modern societies can remain "modern" after another 1859 event given that all transportation, communication, government & business has come to rely on susceptible electronics. I know there are design changes and new power station equipment being installed to minimize such problems, but I've not heard anyone say how long that might be to finish and how much of a solution it really is.
