Firstcolo GmbH

FIRSTCOLO GMBH is a Frankfurt am Main (Germany) data center and colocation provider operating under the firstcolo brand; the company states its Frankfurt sites are TÜV Saarland certified as Tier 3. Public company communications also describe a renaming to firstcolo GmbH effective October 10, 2022.

A publicly listed network footprint exists under AS44066 (firstcolo GmbH), with peering information published in PeeringDB and routing-registry style records visible via BGP directory services. The company’s own materials point to multiple Frankfurt locations (including “Werkhaus” and “AOC”) used for colocation operations.

Online reputation signals are generally positive but mixed by platform: Trustpilot shows an overall strong score (4.x), while some smaller review aggregators contain critical individual reports; independent volume for customer-service reviews appears limited compared with employer feedback. As an employer, Kununu shows a solid rating around 4.1/5 based on dozens of reviews.
