This post is a follow-up to our recent look at DIA vs. Broadband Internet service for business use. Please click

DIA (Dedicated Internet Access) is much different from Broadband service. For starters, it is truly built for business and backed up by enforceable Service Level Agreements. But the difference also lies in how DIA delivers Internet services to end users.

DIA is just what the letters stand for: Dedicated Access to the Internet. Today it is delivered via a direct fiber connection. For smaller bandwidth circuits, a carrier will typically install a NID (Network Interface Device), which serves two purposes. First, it allows the carrier to monitor the circuit for uptime. Secondly, it will change a fiber handoff to a copper handoff for your network edge router/firewall.


Delivery of DIA over a 100% fiber network benefits you in several ways:

  1. Fiber allows for much greater bandwidth. Most carriers today can deliver up to 100Gig’s of bandwidth over a single fiber connection. This also means that once you get fiber built into your location, you are pretty much future proof. Hardware upgrades sometimes need to take place depending on how the service is installed. Nonetheless, from a fiber delivery perspective you should be set.
  2. Having the added capacity of fiber also allows you to receive a symmetrical bandwidth option. In other words, where a Broadband connection may deliver 50Mb/5Mb bandwidth, a DIA circuit will deliver the same speed on the upload and download. Thus, unlike with Broadband services, when you order 50Mb via DIA, you are getting 50Mb on the upload and the download.
  3. Having a Dedicated Fiber connection also means that you really have a Dedicated connection. You do not share a network with your neighbors. No matter what time ofday you are online, you should always receive the full bandwidth that you signed up for.
  4. Fiber is just more reliable than any network that needs to use copper. Copper degrades over time. The glass used in the dedicated fiber connection does not. This helps to create a much more reliable connection. You will be much less prone to issues such as packet loss or jitter, which will create poor performance.
  5. For all of the reasons above and more, the DIA service comes with a SLA (Service Level Agreement) that a business can rely on if any outages or other errors occur. This SLA also comes with stronger penalties if the service does have issues. There are typically metrics for Uptime, jitter, latency, and packet loss. You can also usually negotiate Chronic Outage and a few other benefits into your SLA.
  6. In addition to a more reliable connection and a stronger SLA, you will also receive better support from the carrier. You get better access to engineers at the NOC (Network Operations Center), better escalation paths, dedicated account teams, pre-sales engineering resources, and more. What’s more, GCN’s customers receive world class service and support from our team as well. When you buy from GCN you also receive a dedicated Account Manager, a dedicated Project Management resource, and an additional escalation point across all carriers if and when issues arise.

Going back to the question we asked at the beginning of the first blog, why pay more for what seems like less bandwidth? The answer is simple: Reliability, Dedicated Bandwidth, Better Support, and a Service Level Agreement. When the Internet is business critical, you need Internet access that is built of and for business.

    I like the fact that dedicated internet access allows us the flexibility to add bandwidth capacity as we need it.
