Ping from the Madrid node measures ICMP round-trip time between Ohz Digital's network and your target. To Paris, expect roughly 25ms; Frankfurt around 30ms; Amsterdam around 35ms; London around 28ms. To the US East Coast, RTTs typically fall in the 100–110ms range. To Latin American destinations — São Paulo, Buenos Aires, Mexico City — expect 150–200ms depending on which cable system carries the traffic and how many intermediary networks are in the path.

Spain's position at the southwestern edge of Europe means that ping times to most European destinations are higher from Madrid than from central European nodes. This is purely a function of geography and fibre length, not a sign of poor network quality. When comparing Spanish ping results to those from Amsterdam or Frankfurt, factor in an extra 20–30ms baseline before drawing conclusions about whether a specific target has routing problems on the Spanish path.

ICMP rate limiting exists on some Spanish transit paths, particularly on backbone segments operated by Telefónica and other large Spanish carriers. If the Madrid node shows intermittent packet loss to a target that responds cleanly over TCP, it's worth checking whether the loss is consistent or variable — consistent mid-path loss from a single hop in an MTR trace is usually ICMP policy, while variable loss across multiple hops more likely indicates real congestion.

Spain has a single node on this platform: Madrid, on AS202673, operated by Ohz Digital SL. Madrid is the primary internet hub for the Iberian Peninsula, home to ESPANIX and the DE-CIX Madrid peering point. The Spanish internet backbone is largely centralised in Madrid, with Barcelona as a secondary hub via CATNIX. For most international routing purposes, traffic in and out of Spain passes through Madrid.

Spain's geographic position gives it a unique role in European networking — it sits at the junction between Europe, North Africa, and Latin America. Several submarine cables connect Spain to the Americas, and Spanish carriers maintain direct relationships with major Latin American network operators. Madrid is the natural European gateway for traffic destined for Brazil, Argentina, Mexico, and the rest of LATAM, and CDN operators frequently use Spanish nodes as part of their LATAM serving strategy.

ESPANIX in Madrid is the primary Spanish IXP and handles the bulk of domestic peering between Spanish ISPs and content providers. DE-CIX operates a separate peering node in Madrid that connects Spanish networks to DE-CIX's broader European fabric, giving Madrid-connected networks access to thousands of peers across the DE-CIX platform without needing direct bilateral agreements. CATNIX in Barcelona serves Catalan and northeastern Spanish networks.

Latency from Madrid to the rest of Europe reflects the country's southwestern position. Madrid to Paris is typically around 25ms; Madrid to Frankfurt runs about 30ms; Madrid to Amsterdam is closer to 35ms. These are noticeably higher than intra-core-Europe numbers like Frankfurt to Amsterdam (9ms), simply because of the physical distance through France. To the US East Coast, Madrid shows RTTs around 100–110ms.

Ohz Digital SL is a Spanish hosting and transit provider operating in the Madrid market. The AS202673 network connects to Spanish and international transit providers and peers at ESPANIX and DE-CIX Madrid. Tests from this node reflect conditions typical of a mid-tier Spanish hosting ASN — useful for gauging reachability from Spanish commercial hosting infrastructure without the skew of a major incumbent like Telefónica.
