Comcast is doubling the speeds of two of its most popular XFINITY Internet speed plans, Blast! and Extreme 50, in California. Specifically, the Blast! plan is increasing download speeds from up to 25 Mbps to speeds up to 50 Mbps and upload speeds from up to 4 Mbps to up to 10 Mbps, while Extreme 50 customers will receive download speeds up to 105 Mbps (formerly 50 Mbps) and upload speeds up to 20 Mbps (formerly 15 Mbps).
Comcast is also increasing the speed of its widely used Performance plan by more than 60 percent to 20-25 Mbps downstream and 4-5 Mbps upstream. There is no additional cost to the plans.
