> I know SaaS businesses that don't as they operate in a single country, within a single timezone and the availability needs to be during business days and business hours.

This is a bad road to go down. Management will understand the implication that it's okay to reduce reliability requirements because "we'll just do the dangerous things on the weekends!"

After some time, developers are scheduled every other weekend and when something breaks during daytime, it's not going to be a smooth process to get it up again, because the process has always been exercised with 48 hours to spare.

Then at some point it's "Can we deploy the new version this weekend?" "No, our $important_customer have their yearly reporting next week, and then we have that important sales demo, so we'll hold off another month on the deployment." You get further and further away from continuous integration.
