Looking for the best Dedicated Internet Access providers in Fairfield, CA, USA? 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. Unlike shared broadband, DIA offers a non-shared, guaranteed connection with service level agreements (SLAs) that commit to uptime, bandwidth, latency, jitter, and packet loss.
DIA providers are highly location-dependent, as they require specific network infrastructure to be available in a given area. Providers must have infrastructure at the customer’s building or data center to offer DIA without incurring significant construction costs. This location-based nature means that availability and pricing can vary widely depending on whether a building is already 'lit' or if new construction is needed.
