Business Internet Features to Consider in Gaithersburg
Gaithersburg businesses should look beyond speed when selecting a provider. These six features define the difference between consumer-grade and truly business-class internet:
- Service Level Agreements (SLAs): The best Gaithersburg business providers back their service with 99.9-99.99% uptime SLAs, meaning less than 52 minutes of unplanned downtime per year on dedicated circuits.
- Static IP Addresses: Gaithersburg businesses that need VPN tunnels, security camera remote access, or server hosting require static IP addresses. Business plans from most local providers include at least one in the package.
- Dedicated vs. Shared Connections: Small Gaithersburg businesses often do well with shared cable or fiber plans, but companies needing guaranteed bandwidth should evaluate dedicated fiber circuits that are not impacted by peak-hour congestion.
- Symmetric Upload Speeds: Video conferencing, cloud storage, and VoIP all depend heavily on upload speed. Gaithersburg businesses choosing fiber get symmetric connections, while cable subscribers face upload limitations during heavy use.
- Priority Support: The support difference between business and residential plans is dramatic for Gaithersburg companies. Business accounts get dedicated lines, faster escalation, and repair windows measured in hours, not days.

Business vs. Residential Internet in Gaithersburg
Some Gaithersburg entrepreneurs try to save money by using residential internet for their business. Here is why that approach usually costs more in the long run through downtime, security gaps, and missed opportunities:
- Uptime guarantees: Residential internet has zero uptime guarantees. Verizon Business Fios business plans include SLAs with service credits when uptime targets are not met.
- Upload performance: Residential upload speeds in Gaithersburg rarely exceed 35 Mbps, severely limiting cloud operations. Business fiber connections deliver symmetric speeds where upload equals download.
- Static IP addresses: Residential dynamic IPs change without notice, breaking VPN tunnels, server hosting, and IP-based security systems. Business plans provide stable static IPs essential for commercial operations.
- Terms of service: Operating a business on residential internet in Gaithersburg risks TOS violations that could result in throttling, service suspension, or account termination at the worst possible time.
- Priority repair: Business plans get priority repairs with 4-8 hour on-site commitments. Residential service calls in Gaithersburg can take 1-3 business days to address.
