Calle de Emilio Muñoz 49-51 (MAD3)
Calle de Emilio Muñoz 49-51, Madrid, 28037, ES
MAD3 sits at Calle de Emilio Munoz 49-51, a few streets from the Albasanz pair in Madrid's Julian Camarillo estate. It offers 94,000 sq ft (8,740 sq m) with 2N uninterruptible power and N+1 cooling, and publishes the same ten compliance marks as the rest of the campus, ENS among them. Forty-seven networks reach it, with seven carriers and the NetIX exchange on site. When the Iberian peninsula blackout struck in April 2025, this building's generators picked up the load within about thirty seconds and customer systems ran through it without interruption — a resilience test few facilities anywhere have had under real conditions.
