Does Your Business Need a Dedicated Line? Aggregation vs. Shared Internet

dedicated line vs shared internet

Dedicated lines aren’t fancy—they’re necessary for businesses that can’t afford downtime. Shared connections? They throttle during peak hours, dropping speeds 30-70% whilst dedicated maintains 99%+ consistency. DIA costs more upfront (£800/month versus £100-200), but paired with 99.99% uptime SLAs and real support, it pays itself back fast. Small ops might survive on shared. Anything mission-critical needs dedicated. The real question is whether your business can stomach losing clients over outages—51% of UK businesses experienced them last year. Understanding your actual performance needs reveals everything.

Understanding Dedicated Internet Access vs. Shared Connectivity

With regard to internet connectivity, businesses face a fundamental choice: dedicated lines or shared connections. One’s fundamentally private. The other? Not so much.

Dedicated internet access means a private circuit runs entirely to your business. Your data travels alone on that infrastructure—no strangers hogging bandwidth during peak hours.

Your data travels alone on a private circuit—no strangers stealing bandwidth when you need it most.

Shared connections, meanwhile, bundle multiple users onto one pipe. Basic security measures exist, sure. But they’re not exactly Fort Knox. Dedicated connections enhance security by reducing the risk of exposure to external threats through limited network access.

Here’s the reality: dedicated connections include formal SLAs specifying uptime guarantees of 99.9% or greater. Shared circuits? They typically lack any contractual assurances. One promises reliability. The other crosses its fingers.

Cost-wise, dedicated lines demand higher upfront investment. Shared broadband looks cheaper initially.

But constant downtime drains productivity fast. Sometimes paying more prevents costly headaches later. Encrypted tunnels provide an additional layer of security for businesses requiring secure data transmission across their networks. Modern businesses implementing cloud-based systems require stable connectivity to maintain seamless operations across all platforms.

Performance Differences: Speed, Latency, and Consistency

When someone subscribes to shared internet, they’re fundamentally gambling on bandwidth.

Here’s the harsh truth: dedicated connections deliver 99%+ of subscribed speeds consistently. Shared connections? They crater 30-70% during peak hours. That’s not pessimism—that’s maths.

Latency tells the same story. Dedicated lines maintain a steady 5-15ms. Shared networks bounce between 20-100+ms depending on how many neighbours are streaming Netflix.

Video conferencing turns into a pixelated mess. Upload speeds on shared connections run 10-20 times slower than downloads—brutal for businesses relying on cloud apps or VoIP. Businesses using VoIP or cloud services benefit from dedicated circuits’ steady data streams that prevent service interruption.

The real kicker: dedicated connections guarantee 99.9% performance consistency. With contract-friendly pricing becoming more accessible, businesses can now secure reliable connectivity without breaking their budgets.

Stable uncapped broadband is essential for VoIP effectiveness, as voice quality directly correlates with connection reliability.

Shared connections exhibit 40-60% greater variability. Mission-critical operations need reliability. Shared internet doesn’t cut it.

Reliability Guarantees and Uptime Commitments

Speed and latency matter, sure. But here’s the real talk: if your connection vanishes during business hours, speed becomes irrelevant.

Dedicated Internet Access (DIA) comes with formal Service Level Agreements—legally binding promises of 99.99% uptime. That’s roughly 52.6 minutes of downtime annually. Business Internet? Best-effort service. No guarantees. No accountability.

The difference shows up when things break. DIA providers dispatch technicians 24/7/365 with average repair times around 4 hours. Standard broadband? Good luck reaching someone before Friday afternoon. Aureon delivers both DIA and BI over a fibre-optic, Active Ethernet network with symmetrical speeds available in each service tier.

Service Type Uptime Guarantee Support Hours MTTR
Dedicated Internet (DIA) 99.99% SLA 24/7/365 ~4 hours
Business Internet None (best-effort) Standard business hours Variable/days
Standard Broadband None Limited Unpredictable

Security Considerations for Your Network Infrastructure

Network security isn’t some abstract concept that lives in IT textbooks—it’s the difference between keeping your data locked down and watching it leak across shared infrastructure like water through a sieve.

Dedicated lines eliminate the “noisy neighbour” problem. Your traffic stays yours. No shared pipes means no lateral movement opportunities for hackers who’ve breached someone else’s account.

SIEM systems and intrusion detection actually work when they’re not drowning in someone else’s Netflix buffering. Encryption runs at full speed without bandwidth competition. Access control stays tight.

And when forensic analysis becomes necessary? Complete packet capture happens seamlessly.

Shared internet? It’s a security theatre production where your data plays an extra.

Cost Analysis: Investment vs. Budget Constraints

A dedicated 100Mbps fibre line runs about $800 monthly, whilst the shared equivalent sits around $100–$200.

Quite the gap, right?

Here’s where it gets interesting: dedicated services cost more because they’re actually *yours*. No sharing. No throttling when someone streams Netflix at 5 PM.

That premium reflects real infrastructure investment and support expenses providers bear.

Shared connections use oversubscription—fancy term for cramming multiple customers onto one pipe—to keep prices low.

Works fine if your business doesn’t depend on consistent performance. But mission-critical stuff? VoIP, video conferencing, cloud access? Those apps choke on shared bandwidth during peak hours.

Small outfits under 20 users often survive on shared circuits.

Bigger operations with revenue tied to uptime? That $800 line suddenly looks cheap.

Determining the Right Solution for Your Business

So you’ve got the numbers. Now comes the hard part: actually picking one.

Here’s the thing. Small teams crushing it on email and basic browsing? Shared fibre works fine. Budget gets stretched thin anyway.

But once you’ve got VoIP systems humming, video calls happening constantly, or cloud apps running 24/7, shared connections start looking sketchy. Peak hours turn into a gamble.

Mission-critical operations demand dedicated lines. Full stop. That 99.99% uptime guarantee isn’t marketing fluff—it’s insurance against your business tanking when peak traffic hits.

Remote workforces, cloud-dependent ops, data-sensitive stuff? Dedicated circuits protect you.

The real question: What breaks your business if it fails? If the answer’s “everything,” dedicated’s worth it. If it’s “not much,” shared probably covers you.

Scaling soon? Shared fibre’s flexible enough to grow without gutting your budget today.
