Source: kommunermedipv6.se, latest scan per country (Sept 2026). SPOF = all authoritative name servers sit in one autonomous system (AS) – one network outage takes the domain offline. Counted here: name servers in two or more ASes. Counted per regional domain – regions without a known website are not included. Countries with few regions vary more.
