Looking for the best Dedicated Internet Access providers in San Marcos, Texas? 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 private, uncontended connection offers consistent performance with service level agreements (SLAs) that guarantee uptime, bandwidth, latency, jitter, and packet loss.
DIA providers are highly location-dependent, relying on the availability of specific network infrastructure in a given area. The type of DIA available to you depends on whether providers are "on-net" or "lit" at your building or data center, which significantly affects installation time and cost.
