HUNTSVILLE, Ala. — Comcast announced today that they’re boosting internet speeds for about 80 percent of Alabama (Huntsville, Tuscaloosa, Gadsden, Mobile) customers– at no additional cost. This begins November 6 and continues through December 19.

Depending on your current plan, here are the details:

Blast! speed will increase from 75 Mbps to 100 Mbps
