Dedicated internet access (DIA) is a business internet connection that gives your organisation exclusive, guaranteed bandwidth. You do not share it with neighbours, upload and download speeds are the same, and the service is backed by a service level agreement (SLA). For companies that run on cloud applications, video conferencing and real-time data, DIA is the difference between “usually works” and “always works”.
This guide explains what dedicated internet access is, how it works, how it compares with regular broadband and how to tell whether your business needs it.
What is dedicated internet access?
Dedicated internet access is a network connection reserved for a single customer. With a 1 Gbps DIA circuit, your business has 1 Gbps available at all times, in both directions, no matter how busy the rest of the network is. That is very different from shared broadband, where the advertised speed is a best-case figure that drops when other users are online.
How does DIA work?
An X86 DIA connection follows a simple, short path:
- Last mile to the nearest PoP. Your office, site or rack connects to the nearest X86 point of presence (PoP).
- X86 Internet Gateway (AS133936). Traffic is routed and optimised through our own autonomous system.
- Premium internet. From the gateway, traffic reaches top-tier carriers, internet exchanges (IXs), clouds and content networks directly.
Direct peering is a big part of DIA performance. Because X86 peers directly with major content and cloud networks such as Google, Microsoft, Amazon, Cloudflare and Akamai, traffic to the services your team uses every day takes fewer hops and arrives with lower latency.
DIA vs broadband: what is the difference?
| Dedicated internet access | Business broadband | |
|---|---|---|
| Bandwidth | Exclusive, guaranteed | Shared with other users |
| Upload vs download | Symmetrical | Upload usually much slower |
| Performance at peak times | Consistent | Drops when the network is busy |
| Service level agreement | Up to 99.9% | Best effort |
| Support | 24/7 expert support | Standard helpdesk |
Broadband is fine for light browsing and email. Once your business depends on cloud applications, large uploads or real-time communication, the shared and asymmetrical nature of broadband becomes a bottleneck.
What are the benefits of dedicated internet access?
- Reliable performance: dedicated, high-speed internet that stays fast and uninterrupted every day.
- Symmetrical speeds: uploads are as fast as downloads, ideal for video calls, backups and cloud sync.
- Room to grow: scale your bandwidth as the business grows, without changing provider.
- Security: a dedicated connection is easier to monitor and protect than a shared one.
- Accountability: an SLA of up to 99.9% and expert support available at any time.
Who needs dedicated internet access?
DIA suits any organisation that cannot afford to go offline or slow down, including:
- Data centres and hosting providers that serve customers around the clock.
- Healthcare organisations that rely on cloud records and telemedicine.
- Education institutions running online learning for many users at once.
- E-commerce businesses whose revenue depends on a fast, available storefront.
- Any business that depends on cloud applications, video conferencing and secure data transfers.
How to choose a DIA provider
- Own network and ASN: a provider with its own autonomous system controls routing instead of reselling someone else’s.
- Peering: direct peering with carriers, IXs and content networks shortens the path to the services you use.
- Regional density: strong coverage across Asia Pacific keeps latency low for regional users.
- SLA and support: check the availability commitment and whether support is truly 24/7.
Frequently asked questions about DIA
Is dedicated internet access the same as a leased line?
The terms are often used interchangeably. Both describe a dedicated, uncontended internet connection with symmetrical speeds and an SLA. “Dedicated internet access” is the more common term in Asia Pacific and with global carriers, while “leased line” is common in the UK.
How much bandwidth does my business need?
Start with how many people and systems use the connection at the same time, then add the applications that need the most capacity: video conferencing, cloud backups, large file transfers and customer-facing services. Because DIA is symmetrical, remember to size for uploads as well as downloads. A good provider will help you size the circuit and let you upgrade later without changing the connection.
Is DIA more secure than broadband?
A dedicated connection carries only your organisation’s traffic up to the provider’s network, which makes it easier to monitor, filter and protect. You should still use firewalls and good security practice, but you are not sharing the access network with other customers.
Can DIA be combined with other services?
Yes. Many businesses take DIA alongside private connectivity. For example, they use DIA for internet traffic, data centre interconnect to link their data centres, and colocation to host equipment close to the network. Running everything on one provider’s network means one support team and one point of contact.
