What NTS Workspace does

NTS Workspace AG is a Swiss, owner-managed telecommunications and carrier-neutral colocation operator that has run its own fiber-optic backbone (AS15576) across Switzerland since the mid-2000s. The company operates five data centers — Colobern North² (Uptime Institute Tier IV certified, Bern), Colobern South (Bern), colozüri.ch (Zurich, 400+ racks across three expansion phases), ColoBâle (Basel), and Colozug (Zug) — interconnected by a metro DWDM ring supporting services from 100 Mbps to 100 Gbps+. Beyond raw space and power, NTS offers redundant IP transit (up to 100 Gbps), BGP/multihoming, dark fiber and CWDM/DWDM transport, and both routed (Layer 3) and Ethernet (Layer 2) private network services with managed hardware and configuration support.

The customer base spans Swiss enterprises seeking carrier-neutral colocation, ISPs and enterprise network operators requiring dark fiber or managed transport, multi-site corporates using NTS private networks, and government/municipal entities (notably the City of Bern and eOperations Switzerland, which won a 2021 broadband WAN bid for Bern and Köniz). A content cache for Netflix within the NTS core and select non-profit engagements (International Scout Centre Kandersteg) illustrate the breadth of deployment. NTS is fully owned by its employees, financed through retained earnings rather than outside equity or debt, and operates with a 21–40 person team headquartered at its Wölflistrasse 1d, 3006 Bern facility (built 2017–2019, ~7,500 m² gross floor area, ~1,000 m² office space).

Revenue mechanics are based on recurring monthly colocation (rack, cage, private suite priced per kW base load) plus usage-based IP transit billed at 5-minute intervals against a Committed Data Rate, with private network and transport services on monthly contracts. Distribution is direct enterprise sales with technical sales engineers and quote-based pricing, supplemented by a self-service customer portal (my.nts.ch), industry/community engagement (RIPE training courses, MANRS.org membership), and a curated carrier-neighbor ecosystem at each colocation site. Most recent strategic emphasis is on energy resilience — a 2026 partnership with Inlyte Energy for 2 MW of iron-sodium battery storage by 2028 and collaboration with ETH spin-off Iron Energy on seasonal storage pilots — layered onto a 2021 photovoltaic expansion and SwissGrid balancing-pool participation.

Broad incumbents

• Interxion (Digital Realty): European carrier-neutral colocation operator (now part of Digital Realty) with presence in Zurich. Comparable interconnection and colocation value proposition, competing for the same Swiss enterprise and carrier customers as NTS.
• Swisscom: Switzerland's incumbent telecom operator, also operating colocation and data center services. Overlaps with NTS in fiber backbone, IP transit, and enterprise connectivity, but is far larger and serves a much broader residential and SMB customer base.
• Equinix: Global colocation and interconnection incumbent operating multiple Swiss IBX data centers in Zurich and Geneva. Directly comparable business model but at massive global scale, setting the competitive ceiling for NTS in Switzerland.
• Sunrise (Liberty Global): Major Swiss telecom operator with enterprise data center and connectivity offerings. Comparable to NTS in IP transit, fiber, and colocation but operates at national scale with significantly greater capital and broader product portfolio.

Direct peers

• Green Datacenter AG: Swiss data center and colocation operator headquartered in Zurich. Directly comparable to NTS in carrier-neutral colocation, SwissIX peering, and enterprise hosting, with similar focus on sustainable energy.
• Infomaniak Network SA: Swiss independent cloud, hosting, and data center provider based in Geneva. Comparable independent, sovereign Swiss operator with colocation and connectivity services competing for similar enterprise and public-sector customers.
• Init7 (Schönegg 19 Holding AG): Swiss independent fiber network operator and IP transit provider with its own backbone and SwissIX presence. Closely comparable to NTS's network/transit side (AS-level operations, BGP, RPKI, fiber).
• Safe Host SA: Swiss carrier-neutral data center operator with facilities in Gland (near Geneva) and Zurich area. Directly competes with NTS's Colobern, colozüri.ch, and ColoZug sites for enterprise colocation customers.
• Datapark AG: Swiss independent data center and managed hosting provider with facilities in Zurich area. Comparable mid-sized carrier-neutral colocation and managed services player competing for similar Swiss SME and enterprise customers.

Regional players

• Swiss Fibre Net AG: Swiss joint venture aggregating regional fiber networks to provide wholesale fiber and transport services. Comparable to NTS's dark fiber and transport business, focused on Swiss national footprint.
