Agreed, in fact it's ironic that they try sooo hard to have 100% uptime, as a small amount of downtime, can be a good thing.

No-one cares if vital utility x is working. It's not like they are texting their friends, about x being 'up'.

But if you take away x, often it highlights just how important it was, and it becomes relevant to them.

It reminds them just how much x, means to them.

Then, if x reacts to the adversity in a crowd pleasing way... instant karma and mindshare.
