My company has a rule of no deploys after 5pm (4pm on Friday) minus hot fixes and other special cases. We have unit tests, integration tests, CI/CD, launch new systems/features via flagged code already in production, and we deploy 1-15 times a day to production. Does this stuff prevent regressions, lower issues making into production, and make rolling back simple? Yes. Does it make it infallible? Not a chance. Pull requests can be first in line to go out the next workday, no reason to eat into work/life balance and or company events.
