Looking for the best Dedicated Internet Access providers in Southfield, Michigan? Here's your ultimate guide to making an informed choice.
What is Dedicated Internet Access?
Dedicated Internet Access (DIA) is an internet service where the bandwidth is exclusively yours, ensuring guaranteed, synchronous speeds. Unlike shared connections, DIA provides a dedicated line, offering consistent performance and reliability, backed by service level agreements (SLAs) that guarantee uptime, bandwidth, and other key metrics.
It's important to note that the availability of DIA is highly location-dependent. The specific network infrastructure required for DIA may not be present in all buildings, making it crucial to consider local provider availability and potential construction costs to bring a building "on-net."
