I worked for BlackBerry when outages started to become a thing.

When your business motto is 'always on' - it's really, really bad to be 'off' - it's a deep transgression of the brand promise.

BB was structured poorly for this - they didn't grasp the concept of multiple nodes of redundancy very well. (Easy in hindsight).

But - we should all be impressed at how highly available Google, FB and some other brands are. That's impressive.
