Internet Providers for the San Francisco Bay Area

Let’s start by exploring the technical choices that you have in the Bay Area for your Internet service, while noting the individual pros and cons of each option.

Ethernet over Fiber

The leading providers are AT&T, Level 3/TW Telecom (recently merged), and Zayo.

The Pros of Fiber

  • Superior reliability with strong Service Level Agreements (SLA)
  • Scalable to 10GB
  • Excellent for VoIP

The Cons of Fiber

  • Unless the building is currently “lit” with a fiber connection to the carrier, it can take from 90 to 180 days to install.  AT&T’s lead times are the worst and they frequently don’t deliver within the promised timeframe

Ethernet over Copper (EoC)

The leading providers are TelePacific, Sonic.Net, and XO Communications

The Pros of EoC

  • Many carriers provide the same Service Level Agreements as they do for fiber
  • 45 days or less for installation
  • Recommended for VoIP

The Cons of EoC

  • Maximum capacity is currently 100MB.
  • Does not work past 12,000 to 16,000 feet from the location the EoC equipment is located
  • While many carriers provide good SLA’s, the reliability of EoC is less than fiber, as EoC uses multiple pairs of copper wire, any one of them subject to failure


The only provider in the San Francisco Bay Area is Comcast, which maintains two divisions – Business and Enterprise. Comcast Business delivers asymmetric (download speed is faster than upload speed) service on the same cable as they deliver their video service. Comcast Enterprise is an entirely different operation and they sell fiber Internet connections.

The Pros of Comcast Business

  • Inexpensive
  • Very fast download speeds

The Cons of Comcast Business

  • Asymmetric service, with upload speeds one-fifth the speed of download speeds
  • No Service Level Agreement (SLA) so it’s a “best efforts” product
  • Not the best choice for VoIP
  • Comcast is known to claim that a given address can be served and will take the order, only later to tell the customer that they cannot complete the order. Most times they will ask the customer to foot the bill for extending service to the customer’s building

 The Pros of Comcast Enterprise

  • New network
  • Layer 2 (could be a pro or con)
  • Excellent pricing

The Pros of Comcast Enterprise

  • New to the market
  • Layer 2 (could be a pro or con)
  • Spotty Coverage

Ethernet over Fixed Wireless  

The leading providers Ethernet over Fixed Wireless are TelePacific and WiLine

The Pros of Wireless

  • The service can be installed in two weeks or even less
  • Can be inexpensive

The Cons of Wireless

  • Customer must have line of site to a wireless antenna
  • Service can be negatively impacted by weather
  • Poor choice for VoIP
