I don't think it is working, moreover I don't think it was intended to work. The "ceasefire" targets two things:
1. Elections to Ukrainian Rada. Ukraine needs to stop military actions, at least on paper, to make the elections "lawful"
2. Western press could stop printing disturbing articles about situation in Ukraine, leaving this situation to be solved "behind the curtains" of publicity.
In reality fights continue every day, people die every day and hatred grows between two sides, every day.
