South Africa also has rolling blackouts every few months. We have apps to notify us when it'll happen on our phones. A lot of us have accepted it as normal by now.
I've been on both sides of them: to give information to managers and to get information from people I delegated.
Stand-ups tend to turn into a defensive justification for 'being busy', and distracts from the intended purpose of asking for help.
At my current job, our manager wastes more time interrupting people during their stand-ups to tell them that they are giving the wrong amount of info "that nobody else cares about", instead of listening or helping.
At my previous job, it was used as a way to get people in the office at a certain time.
Your peers don't care about what you're working on, they care about sounding busy.
