Score values: 1.0 = sovereign (EU-hosted, EU provider). 0.0 = non-sovereign (outside the EU, or on a non-EU-controlled provider — US, UK, etc. — regardless of where the datacenter sits). N/A = the sub-score couldn't be measured (no MX record, unresolvable host, etc.) and is excluded from the total.
