A DNS check from Iceland queries your authoritative nameservers directly from our Reykjavik probe node and returns the result. This confirms that DNS resolution is working correctly from Icelandic network infrastructure — useful for GeoDNS configurations that serve different records to Nordic or North Atlantic users, or for verifying that record changes have propagated to the authoritative nameservers as seen from Iceland.

Iceland's DNS infrastructure is small but functional. ISPs like Síminn and Vodafone Iceland run their own recursive resolvers, and public resolvers like Cloudflare (1.1.1.1) and Google (8.8.8.8) are also used. Our DNS check bypasses recursive resolver caches and queries authoritative nameservers directly from the probe node, so you see the current authoritative record rather than a cached value that might still reflect a previous configuration.

If your GeoDNS policy is designed to serve Icelandic or North Atlantic users from a specific origin, a DNS test from our Reykjavik probe confirms whether the geographic routing is working as intended. Iceland's IP space is small enough that some GeoDNS implementations fail to classify it correctly — it might be bucketed under "EU" or "other" rather than a specific Nordic region. A DNS test from Iceland alongside tests from Denmark and the UK lets you compare what different Atlantic-region probes resolve to.

Iceland occupies an unusual position in North Atlantic internet infrastructure — midway between Europe and North America, with submarine cables running in both directions. ISIX (Iceland Internet Exchange) in Reykjavik is the country's main neutral peering point. Given Iceland's small population (around 370,000), the number of networks peering here is modest, but the cables connecting Iceland to the rest of the world are strategically significant for transatlantic routing. IXLeif provides a secondary community peering option for smaller networks.

Latency from Iceland to London runs around 25 ms, reflecting the FARICE-1 and DANICE submarine cable routes to the UK and Denmark. Latency to New York is around 70 ms, which is lower than many European locations due to Iceland's Atlantic position. These figures make Iceland an interesting test location for measuring transatlantic paths — a server that performs well from Iceland at 70 ms to New York is likely on a well-routed path for European transatlantic traffic generally.

Our Reykjavik probe node runs on AS200651, operated by FlokiNET ehf. FlokiNET is an Iceland-registered hosting and colocation provider that explicitly focuses on privacy hosting — accepting customers who need stronger jurisdictional and legal protections than most EU providers offer. FlokiNET operates in both Iceland and Finland, and AS200651 announces routes through ISIX with upstream transit from the major Icelandic carriers. The probe node sits at FlokiNET's Reykjavik data center facility.

Iceland's power infrastructure is almost entirely geothermal and hydroelectric, which has attracted several large data center projects. The combination of cheap renewable electricity, a naturally cold climate for free cooling, and a stable European legal environment has made Iceland attractive for high-density compute workloads and content hosting. Advania and Verne Global operate large data centers in Iceland beyond the smaller colocation market served by FlokiNET.

The main carriers providing Icelandic international connectivity are Síminn (AS30818) and Vodafone Iceland (AS1850), with FlokiNET and others connecting via ISIX and direct transit arrangements. Because Iceland has limited redundancy in submarine cable routes compared to mainland European hubs, a cable cut or outage can affect a meaningful fraction of the country's international bandwidth. This makes Iceland an interesting test point precisely because its connectivity is more constrained and therefore more variable than testing from Frankfurt or Amsterdam.
