DIA stands for Dedicated Internet Access. A “DIA connection” refers to the primary connection for a ISP network (typically fiber or other fast “carrier-grade” or “enterprise-grade” connection) and is a type of internet connection service that provides businesses with a dedicated, high-speed internet connection that is not shared with any other users. This means that the bandwidth is guaranteed and not affected by other users on the same network, ensuring consistent and reliable internet connectivity. DIA typically offers symmetrical speeds, meaning that the upload and download speeds are the same, making it ideal for ISP’s and other businesses that require high-speed data transfer, video conferencing, and other bandwidth-intensive applications. ISPs offer DIA services with varying bandwidth options depending on the network or business needs.
