Partnership Overview
Who BIG Fiber is built for
Hyperscalers (AWS, Microsoft, Google, Meta), data center operators (Digital Realty, Equinix, CyrusOne, Iron Mountain), large carriers needing route diversity, content delivery networks (CDNs), and large enterprises requiring dedicated dark fiber.
Bandwidth IG — renamed BIG Fiber in May 2026 — is a metro dark fiber provider founded in June 2019 and headquartered in Sunnyvale (San Jose), California. It designs and builds 100% buried, high-count dark fiber networks intentionally routed for low latency and route diversity across the San Francisco Bay Area, Greater Atlanta, and Greater Portland. Its Bay Area network spans 167+ route miles and ~289,000 fiber miles on-net to 65+ data centers (including a newly built high-count subsea cable under San Francisco Bay — the first laid for communications in over 20 years), with additional networks in Atlanta (~64 route miles) and Portland (~12 route miles). Customers are data center operators, hyperscalers, carriers, and enterprises. The company is led by CEO James Nolte (ex-AGL Networks/Zayo) and is majority owned by PE firm Columbia Capital, with SDC Capital Partners (2020) and other infrastructure investors (e.g., Stonepeak, La Caisse) holding stakes.
