What it is

The short version

Dedicated Internet Access is a private, symmetrical circuit that belongs to your business and no one else. Upload and download speeds match, throughput is contractually guaranteed, and the carrier owes you service credits when they miss.

We source DIA from over 300 carriers, including Lumen, AT&T, Verizon, Zayo, Crown Castle, and dozens of regional fiber providers. Pricing, fiber availability, and build timelines vary widely by address, so we quote every viable carrier instead of pushing one.

Where it fits

Typical use cases

Revenue-critical workloads

Payment processing, e-commerce, SaaS delivery, and any workflow where an outage stops billing.

Headquarters and data centers

Primary uplink for sites with hundreds of users or co-located infrastructure.

Voice, video, and SD-WAN underlay

Stable jitter and packet loss numbers that hosted voice and real-time video actually need.

Regulated industries

Healthcare, finance, and government workloads where shared broadband fails compliance review.

What you get

From Critical IP, end to end

  • Quotes from every fiber and Ethernet provider serving your address, with construction estimates where required.
  • Project-managed install including LOAs, demarc extension coordination, and turn-up testing.
  • Hard SLAs on uptime, latency, jitter, packet loss, and mean-time-to-repair with carrier-paid credits when missed.
  • Single point of escalation through our 24/7 NOC so your team is not on hold with the carrier at 2am.
FAQ

Common questions

How is DIA different from cable or broadband?
Dedicated Internet is symmetrical and not shared with other tenants. Cable and broadband are shared and asymmetrical. DIA carries financial penalties when the carrier misses uptime or repair targets. Best-effort circuits do not.
What uptime should I expect?
99.99 to 99.999 percent depending on carrier and access type. On-net fiber on a Tier-1 backbone typically lands at 99.99 percent with a four-hour mean-time-to-repair.
How long does install take?
On-net fiber is usually 30 to 60 days. Off-net builds that require construction can run 60 to 120 days. We give you a realistic timeline up front and project-manage every step.
Do I have to sign a long contract?
Most carriers price 36-month terms most aggressively, but 12 and 24-month options are available at every speed. We model the tradeoff so you can choose with eyes open.
