Recent worldwide events have shown that some governments have the ability to dictate citizens right to communication by blocking communication services at will. Such blocking affects individual citizens as well as businesses that have become dependent upon unhindered access to the Internet. It is imperative to take measures in order to avoid blocking these services. We consider a scenario where a region of concern is intentionally isolated from accessing the Internet by its primary

Under the assumption that connectivity to another IISP is available, we prototype and evaluate BGP-based solutions proposed by Alrefai et al. [1] . The prototyping and evaluating of these solutions were performed under conditions designed to capture the real Internet's ASes connectivity layout and traffic conditions. To design automated, consistent and repeatable testing procedures, we created four Java based programs which were able to detect the blocking action of malicious IISPs and measuring network convergence time. The resulting convergence time was in the range of 63 -64 seconds for all of the evaluated solutions.
