South Florida Comcast customers signed up for the Blast! broadband plan are getting noticeably faster speeds from the cable company this week with a free speed upgrade.

Blast! in southeastern Florida used to deliver 16/1Mbps service, but customers in the region are now reporting speeds are up to 20/2Mbps.  PowerBoost, which delivers a temporary speed boost, has also been upgraded to provide improvements in both downstream and upstream speeds at rates as fast as 25/5Mbps.

Comcast will inform customers with outdated cable modems they’ll need to upgrade them to receive the newest available speeds.  All others only need power cycle their existing modem by briefly unplugging it to obtain the new speeds.
