NTT Frankfurt 4 Data Center

NTT Global Data Centers launched the first phase of Frankfurt 4 in 2019 at Voltastrasse 15 in Hattersheim am Main, about 15 km west of central Frankfurt, where land and power are easier to secure than inside the city. The campus opened with building A providing 4,800 sqm of IT space and up to 12 MW of critical load, and has since expanded to more than 14,200 sqm and 34.4 MW in operation; at full build-out the site is planned to reach 32,900+ sqm and 82.3 MW across seven buildings. As a greenfield design it follows NTT's standard for wholesale and enterprise colocation, with carrier-neutral connectivity back into the Frankfurt interconnection ecosystem. The certification set covers ISO 9001, ISO 22301, ISO 27001, ISO 50001, PCI DSS and ISAE 3402. Frankfurt 4 targets enterprises and cloud providers that want scalable multi-megawatt capacity in the Frankfurt market without competing for scarce inner-city space.
