Our read of the numbers

What this means for you

  • Fiber depends on your street. Fiber reaches some homes in California (41%) but not most, so whether your street has it decides your options. Check your exact address before choosing a plan.

  • Gigabit is widely reported. Gigabit plans (1,000 Mbps download, 100 Mbps upload) are reported for 67% of homes. Compare prices across speed tiers; a slower tier can cost less if your household does not need the top speed.

  • You likely have a real choice. 5 non-satellite providers each reach at least a quarter of homes, so many addresses have a real choice. That matters most when a promotional price ends.
