I experienced a flavor of this, too. We had some outages, management said no more daytime deploys, so we had after-hours “deploy parties” whose scope and participant count increased weekly. The smarter managers said it was temporary, but couldn’t say how we’d move back towards continuous deployment. If anything went wrong in any service, you’d end up with a dozen or so folks on a zoom call for 3 hours. We did this once or twice a week.
Went on for about a year, worse each week, before i left.
I've experienced this as well. I call it the "better safe than sorry" strategy, and the issue is it ignores the very real cost of all the extra effort and work, from the literal costs to the slow releases to the loss of people who just can't take it anymore.
