We’ve built 25,000+ miles of fiber so far – and we intend to keep going. Our advanced fiber optic services connect you to virtually unlimited bandwidth and a future-proof network of up to 400 Gbps, with ultra-low latency.

Dedicated Bandwidth

It’s always your bandwidth. Not anyone else’s.

Never share your bandwidth with other businesses. You should only accept full-rate capacity as specified for both upstream and downstream. That’s the kind of service you’ll always get from us. We think this should just go without saying, but apparently some of our competitors haven’t gotten the memo quite yet.

Firstlight outpaces the competition when it comes to download and upload speed.

Guaranteed Reliability

We make other lit services look like they’ve just discovered fire.

Our lit services offer you nonstop, reliable communication with ultra-low packet loss, latency, and jitter. How do we know all this? Because we built the network ourselves. We own and operate it, too.

Reliability & Resiliency

We built our network to be bulletproof, from the ground up.

Our core network is designed to anticipate traffic problems. If one of your connections breaks down, we’ll reroute traffic via another pathway that’s on a wildly different geographical course. And if that one breaks down, we can reroute it, too. Recognizing a pattern? We hope so. It’s our life’s work to ensure your network never fails or falters.
