Internet Service Provider (ISP) filters, intended to block harmful content, frequently lead to **unjustified overblocking**, restricting access to perfectly legitimate websites. This lack of transparency can mean website owners are unaware their content is inaccessible to a significant audience. This service offers a crucial way to check if a website is being blocked by major fixed-line ISPs and mobile networks. By providing **clarity on ISP filtering actions**, it empowers website owners to identify if their site is affected and submit requests for reclassification. This not only helps individual sites regain visibility but also contributes to a broader understanding of **internet censorship** and the extent of overblocking. Millions of households and mobile users have these filters active, often by default, making such checks essential for maintaining **online accessibility** and ensuring **freedom of information**. Users of this tool contribute to a valuable dataset that highlights filtering mistakes, ultimately fostering a more open and transparent internet.
