A multi-lingual computer programmer luddite, but a Goggle outage dis-enfranchised a swag of people using email, calendar, docs etc. Yea, rare, and only for 1/2 hour but if you rely on things for business, a lot can be stolen in 30 mins. Some clever "switched-on" souls couldn't turn their lights on!

You can back up your stuff, you can have two PCs - I bet a lot of us have tablets and smart phones which is tantamount to that.

I have refused any options to use on-line stuff because of the history of dial-up, BT (notso) HotSpots and even my broadband drops out for 2 mins at a pop. The fact that I stick with a really old copy of Office has as much to do with a library of my own programs therein, and experience of past upgrades - compared with a few (few?) hundred GBP.
And owning the process.

The Goggle outage has not been attributed to hacking (or any other cause, note). And just how secure are any "out-sourced" services in the event of a massive solar flare? It will happen, the only question is when?

COVID should have taught us to prepare. But it take time & effort to identify what preparations to take.
