I won't venture a guess on what might be needed on the European power grid, which, IIRC, operates on 220V.
Here in Herrliberg, Switzerland we have probably had about one power-outage per year over the last 5 years. There was one year where we even had two. This is unusual - a lot of places might have just one outage over 5 years. Surges - not a problem. Might happen in combination with an outage, but they're minor.
We use no UPS and no surge-suppression - but the write-cache to the RAID-array does have a battery backup.
That used to be the same here in the Netherlands until a couple of years ago when the powers that be surrendered the energy supply to the free market. In contrast to what everybody says this considerable worsened the level of service and we now are on an average of four power outings a year, mostly in the order of, say, half an hour. Yes, they also increased the price. No surges, however and that is the main thing. The power outings are a nuisance to the desktop user, but relatively harmless. For large systems we have a different story of course. Regards, -- Jos van Kan registered Linux user #152704
