Stockholmer Allee 24, in the Stadtkrone Ost business park at 44269 Dortmund, is DOKOM21's head office and one of the five data centres the Dortmund carrier runs across the Ruhr. Customer racks have been hosted there since 2011. DOKOM Gesellschaft für Telekommunikation, registered at the Amtsgericht Dortmund under HRB 12299, keeps two further sites with recorded interconnection: RZ Huckarde at Fallgatter 11 in 44369, which carries the Ruhr-CIX exchange, and RZ Hörde at Semerteichstraße 167 in 44263. Across the group, more than 4,600 m2 of data centre space is published, with no per-site split. The company's facilities carry TÜV certification to DIN EN 50600 valid to January 2027, documented for the Huckarde building; DIN EN 50600 is a European data centre standard, not an Uptime Tier.
