Most Internet Service Providers (ISP's) provide filters to give users control over the online content that can be accessed in their households. Some ISP's will automatically turn these filters on by default and therefore you might find that access to the Christian Connection site has been blocked.
Each ISP has its own name for this feature (see below) and each operates in a slightly different way, but in general you can manage the filtering online by simply logging in to your ISP account.
The Online Dating Association has produced a guide to Managing ISP Filters which explains how to unblock a site or disable these filters altogether. You can also visit the website for more information from your own provider:
Broadband Genie has also produced a guide to web filters which gives an overview of the options and shows how to manage them on the most popular ISPs.
