Which European countries are covered?
Static Residential ISP covers the United Kingdom, France, Germany, Italy, Spain, Netherlands, Switzerland, Sweden, Norway, Finland, Denmark, Portugal, Belgium, Austria, Hungary, Romania, Croatia, and Cyprus — 18 countries in total, all selectable in the country allocation step of the purchase flow.
That spread is deliberate: localized checks tend to need the specific country a rule applies in, and a pool that only covers the big three European markets forces workarounds for everywhere else.
