I did, multiple times with multiple countries. All of them had some sort of call rotation. Someone was always at the helm, _specially_ in infrastructure and security.
There are whole startups designed to solve this, like PagerDuty.
I am now very curious to understand where your question comes from. There must be some misunderstanding here. You never went on-call or seen a friend do it?
OP said it’s malicious or incompetent to release this on a U.S. holiday weekend. You asked if similar consideration would be given to Brazil. Multiple people chimed in that it would. You’re now pivoting to on-call capacity.
Any amount of on-call capacity can be saturated. That’s why competent multinationals avoid releasing while markets they’re likely to impact are sleeping or drunk. This is a high-level scheduling operation, however, so it’s reasonable for those lower in the organisation to be unaware why an update is being pushed next Tuesday instead of this.
Rotation or always-on isn’t a substitute for being aware of your customers. Good culture permeate this throughout the organisation. Competent ones have someone at the top ensuring controls are followed.
