Today in Mobile

Verizon Wireless has quietly begun throttling data speeds for high-end users, reported late yesterday. In a remarkably evasive statement on its Web site, VZW said it has “implemented new network optimization practices” that will slow speeds for the top five percent of mobile data users when the 3G network is congested. (Verizon also denies that the practice meets the definition of “throttling,” but I don’t understand why not.) The move has received very little attention so far, but it’s just the latest example of how carriers are struggling to deal with increased data usage on their networks.
