Your internet connection is the backbone of your business. Every VoIP call, cloud application, email, and video conference depends on it. Choosing the wrong provider can cost you thousands in lost productivity, dropped calls, and frustrated customers.
This guide walks you through the five key factors to evaluate when choosing a business internet provider — plus the questions to ask and red flags to watch for.
5 Key Factors to Evaluate
1. Speed Requirements
Match your bandwidth to your staff size and usage patterns. A 10-person office running VoIP, cloud apps, and video conferencing needs at least 50–100Mbps symmetrical. Don't just look at download speeds — upload speed matters equally for VoIP and cloud backups.
2. Latency
Latency is the delay between sending and receiving data. For VoIP calls and real-time cloud applications, you need latency below 30ms. High latency causes choppy calls, lag in cloud apps, and poor video quality. Ask your provider what their average latency is on business routes.
3. Uptime SLA
An uptime SLA (Service Level Agreement) is your provider's guarantee of availability. Aim for 99.5% uptime or higher. Here's what different SLA levels mean in practice:
- 99.0% — up to 7.3 hours downtime per month
- 99.5% — up to 3.65 hours downtime per month
- 99.9% — up to 43 minutes downtime per month
If your provider doesn't offer an SLA, that's a major red flag.
4. Support Response Time
When your internet goes down, every minute counts. Look for a provider that offers a 1-hour response SLA for critical issues. Ask about their support channels — do they have phone, email, and ticket systems? Is support available 24/7 or only during business hours?
5. Redundancy Options
No single link is 100% reliable. Your provider should offer failover options such as backup LTE or a second fibre link on a different route. Automatic failover means your business stays online even if the primary connection drops.
Questions to Ask Your Provider
Before signing any contract, ask these critical questions:
- What is your uptime SLA? — Get it in writing with penalty clauses.
- Do you offer failover? — Backup LTE, secondary fibre, or SD-WAN?
- How do you monitor links? — Proactive monitoring catches problems before you notice them.
- What are your response times? — Specifically for critical outages vs general queries.
- Are there hidden costs? — Installation fees, router rentals, early termination penalties, bandwidth overage charges.
Common Red Flags
Walk away if you encounter any of these warning signs:
- No SLA — If they won't commit to uptime in writing, they can't be trusted with your business connectivity.
- No proactive monitoring — You shouldn't be the first to know your link is down.
- Long support delays — If it takes days to get a response during sales, imagine what support will be like.
- Unclear billing — Vague pricing, unexplained fees, or contracts that are difficult to understand.
