DNS Landscape in Portugal
Portugal benefits from western European internet infrastructure with strong connectivity to the Marseille and Madrid IXPs. Lisbon hosts the Portuguese Internet Exchange (PX) and connects to major European hubs. Most major public DNS resolvers have points of presence in Lisbon, with good coverage across Porto and northern Portugal.
Cloudflare DNS (1.1.1.1) averages 12 ms in Lisbon and 14 ms in Porto. Google DNS (8.8.8.8) averages 14 ms in Lisbon and 16 ms in Porto. Quad9 averages 13 ms in Lisbon and 15 ms in Porto. In the Algarve and southern regions, latency increases slightly to 16-22 ms.
Performance Rankings
Cloudflare 1.1.1.1 is the fastest option for most Portuguese users, averaging 12-14 ms in Lisbon. Google 8.8.8.8 is competitive at 14-16 ms. Quad9 performs well at 13-15 ms. NextDNS averages 15 ms. OpenDNS averages 18-24 ms. Portugal's position on the Atlantic edge means US-hosted content performs particularly well.
