Looking for the best Dedicated Internet Access providers in Marietta, Georgia? Here's your ultimate guide to making an informed choice.
What is Dedicated Internet Access?
Dedicated Internet Access (DIA) is a type of internet service where the connection is provisioned specifically for a single customer, ensuring guaranteed bandwidth that is not shared with other users. This means that if you purchase a 100 Mbps DIA circuit, you are guaranteed to receive 100 Mbps of bandwidth 100% of the time.
It's important to note that DIA providers are highly location-dependent. The availability of this service hinges on whether the provider's network infrastructure is present in your area. This means that the type of DIA available to you can vary significantly based on your location, impacting both cost and service quality.
