I am having same issue. I have contacted Comcast and every customer service representative tells me that I have received this information in error.
Based on advertising, Blast speed is supposed to double, from 25 - 50Mbs. I still measure at 25Mbs.
I live in NH, just north of Boston.
Here is the Contact #'s given to me from Comcast: Case ID 11052448
