MTR from the Madrid node traces the full network path from Ohz Digital's Spanish network to your target, showing each hop with latency and loss data. Traces heading to France will typically exit Spain through the Pyrenees corridor, entering France near Hendaye or the Perpignan–Barcelona axis before continuing north to Paris. The first few hops out of Madrid into French territory are a common location for asymmetric routing — the outbound path may differ from the return path.

For targets in Latin America, MTR from Madrid is particularly informative. The trace will show which submarine cable carries the traffic — routes via the SAT-3/WASC/SAFE cable or the Columbus III system produce different hop patterns and latency profiles. Seeing which Spanish carrier picks up the traffic and which cable landing station it exits through tells you a lot about why the RTT to a specific LATAM destination looks the way it does.

Interpreting MTR from the Madrid node requires the same care as any ICMP-based trace: routers that drop or rate-limit ICMP TTL-exceeded messages will appear to show 100% packet loss in the middle of an otherwise working path. On Spanish backbone infrastructure operated by Telefónica and other carriers, this is common. As always, focus on whether high loss or latency at a specific hop persists through all subsequent hops — that's the real signal, not the individual hop's ICMP response rate.

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.
