Madrid, live since 2025, sits in MAD1 in Alcobendas, a Tier III+ building on the city's business ring road where the ESpanix fabric runs. It was our first Iberian port, and the first week of test traffic made the sales case for us: Lisbon answered at 5 ms, and São Paulo — the other end of the peninsula's cable habit — came back at 101 ms.
The site carries 0.32 Tbit/s of edge capacity on Arelion, Cogent and Lumen at a 3 ms local median, with 14 ms to Frankfurt and 78 to New York. Madrid is the answer for Spanish users who had been quietly renting in France or Germany because nobody offered them a local rack; the flat price means they were never saving anything by the detour.
