Many people here aren't in America either, but from the American perspective:
You have a right to demand partial refunds for service outages. I once spent several hours of my life getting a <$5 credit from Comcast for a day-long outage.
They sent a tech over to install a new router and I enjoyed faster, uninterrupted service for the remainder of my tenancy, so I count it time well spent.
The "Europe" qualifier seemed necessary as many people on here aren't in Europe.
