Data Caps Among Castlewood Internet Service Providers

Many Internet providers have been moving to increase the use of "data caps" to their home broadband plans lately. The trend is certainly true for the Castlewood market, with common ISPs like Mediacom selling capped plans. This won't matter for the majority of Internet subscribers, but might affect users that download or upload a lot of high-def content. If you have data use concerns, start by checking for fiber plans in your area using the search tool at the top of this page. Fiber is frequently a bit higher priced, but can offer unlimited data and streaming because the fiber infrastructure doesn't share cable or DSL's bandwidth ceiling.
