Colocation-Site Digital Realty Vienna

The Best-Connected Location for Your IT

The data center with Austria’s best network has been expanding on what used to be an industrial site in Vienna Floridsdorf since the year 2000. Digital Realty Vienna is accessible via fiber-optics with multiple redundancies. You can find practically every Austria-based carrier and ISP on site, including a PoP of the Vienna Internet Exchange VIX. The continued expansion in a redundant room-within-a-room concept is state-of-the-art and Digital Realty has achieved all industry-standard certifications.

next layer operates a fully redundant network node with multiple external fiber connections at this site, and several fully separated hot/cold aisles for colocation and cloud services in different fire compartments. Our most recent expansion stage is the construction of the particularly powerful component VIE2.
