That doesn't sound so good. Not even here in Armenia, which is tiny, poor and geographically isolated by an economic and military blockade by its neighbours (80% of the land borders of the country) Turkey and Azerbaijan, and 40% of whose power comes from a long-outdated Soviet nuclear power plant (Metsamor), are power blackouts common. In September, there were two outages in the section of Yerevan in which I live, lasting about 5 hours each, and people were absolutely furious. I was told this was highly anomalous, on the order of once-in-a-few-years. It hasn't happened again. I would expect more from Capital Federal.
