The most widely available technology is Fiber, covering an estimated 75% of the city by mid-2026, representing a significant 20% increase from 2025 due to ongoing municipal fiber buildouts.

Fastest Internet Providers in Cotati, CA

The fastest internet provider in Cotati, CA, in 2026 is AT&T with speeds up to 5 Gbps via Fiber, following their extensive network expansion and upgrade initiatives. Xfinity follows closely with symmetrical gigabit speeds available in many areas as part of their DOCSIS 4.0 rollout by mid-2026.

In 2026, achieving the highest internet speeds in Cotati is primarily driven by fiber-to-the-home (FTTH) deployments.
