Earlier this year, Bandwidth IG became BIG Fiber, a bold new name that reflects where we’re headed and what we’re building.
Since day one, we’ve focused on one thing: delivering purpose-built dark fiber infrastructure for the largest consumers of bandwidth in the world. With AI, cloud, and data workloads scaling faster than ever, our networks and our identity needed to match that momentum.
BIG Fiber isn’t just a rebrand. It’s a signal that we’re thinking bigger, building faster, and staying laser-focused on what the market really needs: high-capacity, modern, underground fiber that’s ready for what’s next.
Milestones on our Journey
We’ve grown a lot during our short existence as a company. Since being founded in 2019, we’ve progressed from a single 5-mile dark fiber ring in the Santa Clara, California, area to now being a multi-market provider of purpose-built dark fiber.
We’ve laid more than 600 route miles of newly built dark fiber infrastructure across the San Francisco Bay Area, Greater Atlanta, and Greater Portland, with more underway. From the groundbreaking Bay Crossing under San Francisco Bay to new builds designed around hyperscaler needs, BIG Fiber is setting a new standard in dark fiber design and deployment.
Here are a few key highlights:
- 2019: Founded in Silicon Valley with our first dark fiber ring and expanded into Greater Atlanta as the first pure-play data center-to-data center provider.
- 2023: Commenced a 170-mile route expansion across Greater Atlanta metro.
- 2024: Completed a 310-mile San Francisco Bay Area expansion, including the first new subsea fiber under the San Francisco Bay in over 20 years.
- 2025: Rebranded as BIG Fiber to reflect our momentum.
Our growth is a reflection of the clear and present need for more digital infrastructure services, and the continued trust our partners place in us to deliver that service. Thanks to this sentiment, our customers have made us one of the top providers of dark fiber services in two of the most dynamic North American data center markets – San Francisco Bay Area and Greater Atlanta – and a key provider in the emerging Greater Portland market.
The Future of Dark Fiber
While our name may have shifted, we assure you our mission to empower digital technologies that transform our lives remains steadfast. Our focused team adapts quickly and we unapologetically go where other fiber providers don’t to provide our customers with truly diverse options.
As CEO, Bruce Garrison put it, “Our new name matches the scale of our ambition. We’re here to support customers powering the AI era—and we’re just getting started.”
With fresh investment, a growing team, and eyes on the horizon to new markets, BIG Fiber is ready to help carry the future.
Same mission. Bigger name. BIG Fiber.
