I don't know which industry you worked in, but outages in the telecom industry was strictly forbidden and came with severe financial penalties even 10 years ago. And those companies managed to adhere to really strict uptime SLAs even then.

It might take less resource today though to achieve the same, I agree with that.

Telcos have historically had availability regulations in many places because of how people rely on them for access to emergency services. So they’re a special case here, and the amount of resources they invested into optimizing for that is beyond the capacity for most organizations.

10 years ago I was working for a company that provided a financial OLTP service. We had to invest a huge amount of money to be able to provide a reasonable HA architecture, and to be able to meet 4 hour DR SLAs, and we still had weekly maintenance outages. The amount of effort required to accomplish those service levels today is comparatively trivial, and you could reasonably expect even a low-budget one person operation to be able to exceed them.

You’d expect a service outage to be a significant public controversy today for a lot of companies. It’s never been a good thing, but we’ve come a long way from it being a completely routine event for most services. Especially given the explosion in online services.
