Comcast recently announced that it may soon begin charging additional fees to broadband Internet subscribers who go over their monthly bandwidth allowances. The cable operator currently suspends customers’ service if they repeatedly go over their 250GB monthly data allowances rather than charging any penalties. Instead of capping broadband customers at 250GB per month, however, Comcast plans to raise the cap to 300GB and charge $10 for each 50GB block of data above that limit, Digital Trends reported. The change is currently being tested with select customers but if successful, the company plans to implement the change across its network. Comcast began capping data in 2008, and it claimed the measure was necessary in order to manage its network.
