I guess people learned how to adapt. After months (yes, months) of daily blackouts, no one was complaining about it. Everyone was even expecting (and welcoming) its onset. The staff were trying to cope up with it. They were doing double time when the lights are on but it wasn't enough. The blackout was everyone's excuse for unfinished tasks.
However, it was different for the patients (and their relatives). I could only imagine the terrible discomfort they must be feeling. The delay in the health services they are hoping for must be infuriating. And I have encountered some of their anger whenever I was assigned in the help desk in the waiting area. I wasn't much of a help.
The blackout problem is now fixed and work goes back to the regular abnormally stressful level. Downtimes are rare. And breathers like it are always welcome.
