It does seem crazy that you weren't told of the attempts to break in before the last minute.

I had not thought about how the load shedding times being on a set schedule would give criminals plenty of time to plan their crimes in advance. It is bad enough hearing about the personal inconveniences of it all, but having to consider the possible crimes that can occur at the same makes it a lot worse.

It is good you have knowledge of what to look for and how to adjust to make things as safe as possible.
