I disagree, from a certain point of view. Consider the CDN. One customers downtime is the IRS’s filing date. The IRS’s slow time is during the Super Bowl. The NFL’s season of rest is baseball season. Baseball goes dark on cyber Monday.
When should the CDN undertake updates? Continuously.
(Obviously I do get your main point: the NFL should not upgrade at halftime of the Super Bowl. But there is a time and a place for different models.)
I think we actually agree with one another. Code freezes/deployment windows should be justified by business risk, not idealised always be pushing mentality.
CDNs and cloud providers are a bit of a special case. AWS definitely has soft blocks during tax peak and large sporting events, CDNs (guessing here) would likely be doing follow the moon(?) (i.e. off-peak) rolling releases
My disagreement with the parent comment was driven by lack of nuance
