Do you use Google Drive to host custom CSS files, JS files in FSB stores safely?

Hi @Carey Baird … I would love to hear your comments on this.

As you may have noticed, I like to customize my sites a bit.
I'm currently hosting all my custom css and js files from a master site which, in turn,
feed all my other sites.

I have spent a lot of time and effort in personalization. I'm afraid that if my master site crashes or worse, all other sites will be too, because they depend on the files css & js provided said master site.

These concerns have led me to think about additional security methods / services for the main site.
I had a thought, Google Drive? What's more stable and secure than a google server. Right?
Based on the light research that I have done, it is technically possible to do it.

What are your thoughts?

Thank you!
