Doubling speeds of many broadband tiers.

Broadband Reports has a reliable source inside Comcast that says faster speeds are on the way for customers across the country, beginning in March.

Last summer, an anonymous tipster shared a preview of Comcast’s “All New Xfinity” broadband offerings. BR is reporting the speeds seem to be mostly spot-on, but will come at a price of around $2 higher than shown in the graphic.

• Comcast’s Blast tier is increasing from 25/4Mbps to 50/10Mbps starting in March;
• Extreme will be going from 50/10Mbps to 105/20Mbps starting in March;
• Performance will essentially double in speed from 12/2Mbps to 25/4Mbps beginning in May.

Comcast is likely to gradually roll out speed increases across its service area, but some older systems serving smaller communities may have to wait longer.

BR also notes Comcast seems to be gradually decommissioning its PowerBoost feature, which delivered a temporary speed increase at the start of file downloads and streaming video. When the new, faster speeds arrived in the northeast, PowerBoost was discontinued.
