Your normal experience is far outside what most people in Europe would prepare for, so our comments on this thread should probably be ignored by North Americans. Looking at [1], I can see only two power cuts lasting more than 24 hours (Barcelona, 2007 and Cyprus, 2011). Instead, "major power cut" refers to things like "The power cut occurred at 4:20 pm and power was slowly restored between 5:20 and 6:30 pm." (Glasgow, 2009.) I can't remember being without power for more than 6 hours, and it's probably more like 3 or 4. I've been responsible for some colocated servers for about 8 years, and there's been one occasion where grid power was lost. That was about 20 minutes. A Raspberry Pi I have in a village in England has lost power once in the last three years.
