Comcast decided to enforce the announced restrictions on its service usage and starting with October 1 anyone exceeding 250 Giga Bytes of data a month will first be warned and if caught doing it again, their service will be suspended for one year.

The company explained that it will not provide any sort of tool to monitor the bandwidth usage and users will have to search for one online.

The explanation for such a move was offered in the official announcement: "250 GB/month is an extremely large amount of data, much more than a typical residential customer uses on a monthly basis. Currently, the median monthly data usage by our residential customers is approximately 2 - 3 GB." Looking to make things even clearer, the company’s officials gave examples of things that users could do with their 250 GB: they could send 50 million e-mails, download 62,500 songs, download 125 standard-definition movies or upload 25,000 hi-resolution digital photos.

According to Comcast’s estimations, about 99 percent of its 14 million user base will not be affected by the new rules and the rest will have to find a way of better calculating their actions. The move is expected to ensure a better Internet delivery among all of the company’s Internet subscribers which until now was degraded at times by the minority of heavy users.

These rules are being considered by all the cable and phone companies, with activities such as photo-sharing, watching on-line videos and music downloads becoming more and more popular, constantly and significantly increasing the usage.
