Short answer
Dedicated Internet Access (DIA) makes sense when best-effort broadband is no longer enough. Common signs are application or transaction failures on broadband, audit or regulatory requirements for enforceable performance, a move to international cloud platforms, or a redesign of core sites where stable international routing matters more than headline speed.
In detail
Signals that point to DIA:
- Transactions, voice or business applications fail or degrade on broadband
- Auditors or regulators require enforceable performance and accountability
- Workloads are moving to international cloud platforms
- A head office, data centre or SD-WAN hub is being redesigned
- The organisation operates in financial services, government or healthcare
What DIA gives you: dedicated 1:1 contention on local and international traffic, symmetric committed bandwidth that does not degrade at peak, predictable latency, jitter and packet loss, static public IPs, and defined SLAs with service credits aligned to the carrier.
DIA is not intended for price-only branch access or guest Wi-Fi, where business broadband is the better fit. Many estates use both: DIA at core sites and broadband at branches, with broadband also serving as a cost-effective backup to DIA.
