You have to live in a warmer climate to be on the list of the next eight cities to get Time Warner Cable’s massive Maxx upgrade.

This afternoon, Time Warner announced it would more than triple the broadband speeds of customers in Austin, Charlotte, Dallas, Hawaii, Kansas City, Raleigh, San Antonio and San Diego at no extra charge.

“We are committed to reinventing the TWC service experience market-by-market,” said Time Warner Cable CEO Rob Marcus. “We want our customers to know a new experience is coming that brings them super-fast Internet speeds and a more advanced TV product.”

Most of the cities on the upgrade list either have or are at least facing the threat of fiber-based competition from AT&T or Hawaiian Telcom. With Verizon’s long-suspended FiOS project and Frontier’s ‘DSL or Die’-philosophy, Time Warner Cable has so far avoided spending money on upgrades where its only significant competition comes from DSL. Outside of New York City, Time Warner has yet to announce any upgrades within its northeast division, which dominates cable service in Maine, western Massachusetts, New York, and parts of Ohio.

With both Google and AT&T promising fiber service in Austin, Time Warner wasted no time beginning upgrades in the capital city of Texas, which have already delivered faster Internet speeds across large sections of the city. By the end of this week, more than half of Time Warner’s broadband customers in Austin will have access to free upgraded speeds.

TWC customers in these communities who subscribe to the Standard Internet plan, formerly up to 15Mbps, will now receive up to 50Mbps, and customers who subscribe to the Ultimate plan, formerly up to 100Mbps, will receive up to 300Mbps – more than three times their current speeds, at no extra charge. In non-upgraded areas, Time Warner’s maximum speed remains 50/5Mbps.
