The Business Case for 10Gb Leased Lines: Why Now is the Time to Upgrade

Is your 1Gb connection quietly costing you more than you think?

If you’re running a business in 2025, the question isn’t whether you need fast internet anymore. The question is whether your current connection can keep pace with where your business is actually heading. For many companies still operating on 1Gb leased lines, the answer is increasingly becoming “no.”

The good news? Upgrading to 10Gb capacity has never been more accessible. Prices have dropped dramatically over the past few years, and the performance gap between 1Gb and 10Gb isn’t just incremental—it’s transformational.

Understanding the real-world difference

Let’s be practical. When we talk about 10Gb leased lines, we’re not just discussing a number that’s ten times bigger. We’re talking about fundamentally different operational capabilities for your business.

What Does 10Gb Actually Mean for Your Daily Operations?

A 1Gb connection transfers roughly 125 megabytes per second. That sounds impressive until you consider what modern businesses actually do:

• Video conferencing across multiple teams simultaneously Each 4K conference call consumes 15-25 Mbps. With remote and hybrid working now standard, you might have 10, 20, or 30 calls happening at once.

• Cloud backup and synchronization Modern businesses backup terabytes, not gigabytes. On a 1Gb line, backing up just 1TB takes over two hours. On 10Gb, it’s done in 13 minutes.

• Large file transfers Whether it’s CAD designs, video production files, medical imaging, or software builds, professional files have exploded in size. A 50GB project file that takes 6.5 minutes on 10Gb would take over an hour on 1Gb.

• Real-time collaboration Design teams using Figma, engineering teams with live development environments, finance teams with real-time analytics—these aren’t future scenarios. They’re happening right now in your business.

The 2:1, 5:1, and 10:1 Options: Finding Your Sweet Spot

One of the most significant developments in recent years is the availability of flexible contention ratios for 10Gb services. This is where the economics become genuinely interesting for businesses currently on 1Gb.

What is a Contention Ratio?

Traditional 1Gb leased lines offer a 1:1 contention ratio—you get dedicated, unshared bandwidth. But with 10Gb infrastructure now widespread, providers can offer more flexible options that dramatically reduce costs while still delivering exceptional performance.

Here’s how it works:

Why These Options Change the Game

For IT managers, this is significant because overprovisioning is now affordable. Rather than constantly managing bandwidth scarcity, you can finally architect for abundance. And for finance directors, the message is equally clear: these options deliver 10Gb infrastructure economics that often rival what you’re currently paying for 1Gb.

Direct Comparison: 1Gb vs 10Gb Performance

Let’s compare real business scenarios:

Scenario 1: Multi-Site Video Collaboration

Your situation: Monthly all-hands meeting with 200 employees across 8 offices, plus daily team standups

On 1Gb:

• Video quality automatically degrades to 720p or lower

• Screen sharing becomes choppy

• Some users report audio cutting out

• IT receives complaints after every large meetingEmployees join from personal devices on mobile data to ensure reliability

On 10Gb (even at 10:1 contention):

• All users maintain 1080p, with 4K available for key presenters

• Screen sharing is seamless, even with animation-heavy slides

• Concurrent breakout rooms don’t impact quality

• Recording and streaming happen without affecting participant experience .Your unified communications platform performs as designed

Scenario 2: Cloud-First Operations

Your situation: You’ve migrated to Microsoft 365, Salesforce, and cloud-based design tools

On 1Gb:

• Opening large PowerPoint presentations from SharePoint takes noticeable time

• Salesforce reports with extensive data load slowly

• AutoCAD or Revit cloud collaboration experiences lag

• Cloud rendering queues up rather than processes in real-time

• End-of-month close takes longer due to system responsiveness

On 10Gb:

• Applications respond as if they’re installed locally

• Large dataset manipulations happen in real-time

• Multiple teams can pull extensive reports simultaneously

• Cloud rendering processes immediately

• Your cloud investment delivers its full ROI

Scenario 3: Business Continuity and Backup

Your situation: Nightly backups, disaster recovery replication, and compliance requirements

On 1Gb:

• Backup windows extend into business hours

• Incremental backups are prioritized, full backups happen monthly

• DR testing is scheduled carefully to avoid impact

• Backup traffic competes with production workloads in early morning

On 10Gb:

• Full backups complete in fraction of the time

• Continuous data protection becomes viable

• DR replication happens in real-time

• Backup traffic is negligible compared to available capacity

• Compliance requirements are easier to meet
