Wholesale and enterprise fiber in Colorado
Zayo Colorado
A pure infrastructure company. Dense metro fiber rings and national long haul, sold to enterprises and to other carriers.
Zayo is headquartered in Boulder and its Colorado metro fiber reflects that. It is strong in Denver and Boulder, strong into data centres and carrier hotels, and largely irrelevant to a small office that does not sit near one of its routes. This is an infrastructure company, not a small business ISP.
Where Zayo is strong
- Very strong in metro rings, data centers, and carrier hotels
- Excellent for point to point, dark fiber, and wavelength requirements
- Frequently the underlying network beneath someone else's branded service
- The Crown Castle acquisition widened the on-net building list considerably
Zayo in Colorado specifically
- Dense metro rings in Denver and Boulder, plus long haul through the state.
- Excellent for data centre connectivity, dark fiber, wavelengths and multi-gig point to point.
- Frequently the underlying network beneath another provider's branded service.
- Absorbed Crown Castle's fiber business on 1 May 2026, which widened the on-net building list in the Denver metro.
- Proximity to an existing Zayo route decides everything. Being in a Zayo city is not the same as being on a Zayo route.
Best fit. Data centre connectivity, high bandwidth transport, dark fiber and carrier grade requirements.
What to watch for before you sign
- Reach is route based, not blanket coverage. Being near a Zayo route matters more than being in a Zayo city.
- Better suited to buildings with real bandwidth requirements than to small offices.
- Since May 2026 a Crown Castle Fiber quote is a Zayo quote. Do not treat them as two bids.

What a Colorado business pays, and how to judge a quote from Zayo
Business internet is priced per address, so there is no Zayo rate card anyone can hold them to. What follows is what businesses in Colorado typically pay at a building that is already lit, whichever carrier serves it. Use it to judge the quote you get.
| Bandwidth | Dedicated internet, monthly | Business fiber broadband, monthly |
|---|---|---|
| 50 Mbps | approximately $329 | approximately $100 |
| 100 Mbps | approximately $369 | approximately $100 |
| 200 Mbps | approximately $464 | approximately $150 |
| 500 Mbps | approximately $499 | approximately $200 |
| 1 Gbps | approximately $680 | approximately $400 |
| 10 Gbps | approximately $2,500 | approximately $2,500 |
What installation usually costs
| Situation | Typical up front cost | What is happening |
|---|---|---|
| Building already lit | $0 to $500 | The carrier is already inside. A cross connect and a router. |
| Short lateral build | $0 to $15,000 | Fiber runs nearby. Carriers often absorb some or all of it on a longer term. |
| Long or difficult build | $15,000 to six figures | Real construction. Permits, trenching, possible crossings. |
Contract term
- 36 months is the usual starting point for business fiber and dedicated internet. 12 and 24 month terms exist and normally cost more per month.
- 60 months buys the biggest discount and the largest construction contribution, which is why it is worth pricing even if you do not sign it.
- Ask for the construction charge at 36 months and at 60 months as two separate numbers. That gap is the real negotiation.
- Check the renewal and the annual escalator before the monthly price. A cheap year one with an automatic uplift is not a cheap contract.

Zayo in Colorado: common questions
Is Zayo available at my Colorado address?
Carrier footprints change constantly and no public map is accurate at the building level. We check serviceability directly with each carrier before telling you what you can get. Give us the address and we will confirm with Zayo directly, along with every other carrier that could reach it.
How much does Zayo business internet cost in Colorado?
Business internet is priced per address, so there is no Zayo rate card to quote, and a site that shows you one is guessing. In Colorado we typically quote approximately $329 a month for 50 Mbps of dedicated internet and approximately $680 for 1 Gbps, at a building that is already lit. Business fiber broadband at 1 Gbps typically runs approximately $400. Construction, contract term and which carriers reach the building move the real number.
Is Zayo the cheapest option in Colorado?
Sometimes, and it depends almost entirely on whether your building is already on their network. A carrier who is already in the building will normally beat a carrier who has to build, regardless of list pricing.
Can I buy Zayo through you at the same price?
Yes. Pricing is the same as going direct. The difference is that you get every other carrier's number at the same time, and you are not managing the process yourself.
Check Zayo availability at your address
We will confirm whether Zayo can serve you, and quote every other carrier that can reach the building at the same time.
