Business Internet Features to Consider in Fullerton
Speed matters, but it is only one factor in selecting business internet for your Fullerton company. Consider these essential features when evaluating providers:
- Service Level Agreements (SLAs): The best Fullerton 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: Without a static IP, your Fullerton business cannot reliably host servers, maintain VPN connections, or run certain POS systems. Business plans typically include one, with additional IPs available in blocks.
- Dedicated vs. Shared Connections: Shared connections (cable, standard fiber) offer great value for small businesses, while dedicated fiber provides guaranteed bandwidth not affected by neighborhood usage peaks. Fullerton businesses with mission-critical operations should consider dedicated circuits.
- Symmetric Upload Speeds: As Fullerton businesses move more operations to the cloud, symmetric upload speeds become critical. Fiber plans offer true symmetry, while cable business plans cap upload at a fraction of download speeds.
- Priority Support: Fullerton business internet customers receive priority support with faster response times. Most providers commit to 4-8 hour on-site repair windows, compared to 24-72 hours for residential service.
- Scalability: The right Fullerton business internet plan grows with your company. Look for providers offering bandwidth-on-demand or quick tier changes that do not require new contracts or extended installation windows.
Business vs. Residential Internet in Fullerton
The price difference between residential and business internet in Fullerton often makes business owners question whether upgrading is worth it. These key differences show why business-grade service pays for itself:
- Uptime guarantees: When residential internet goes down, there is no SLA protecting your business. AT&T Business Fiber and other business providers offer guaranteed uptime with credits for any shortfalls.
- Upload performance: Residential cable plans in Fullerton typically cap uploads at 10-35 Mbps. Business fiber plans deliver symmetric speeds up to 5-10 Gbps for cloud backups, VoIP, and video conferencing.
- Static IP addresses: Static IPs from business plans support VPN tunnels, remote access, payment compliance, and server hosting. Residential IPs change periodically, causing unpredictable disruptions to these services.
- Terms of service: Operating a business on residential internet in Fullerton risks TOS violations that could result in throttling, service suspension, or account termination at the worst possible time.
- Priority repair: Downtime costs money. Business internet repair in Fullerton is typically completed within 4-8 hours, while residential customers wait 1-3 business days for a technician.
