The lengths governments are going to to block websites is getting sophisticated by the day, in Bangladesh users are reporting that Youtube, the video sharing site has been inaccessible since Friday.  Other file-sharing sites like esnips and mediafire are facing the same fate.

Apparently these sites have been blocked at the International Internet Gateway (IIG) level as they can be accesses through proxy.  In essence Bangladeshi gateway providers are blocking this sites.  Global Voices reports that:

Mango and BTCL (formerly BTTB) are the official IIGs (International Internet Gateway) in Bangladesh. Starting last April, by regulation, all Bangladeshis ISPs have to route their international traffic to either Mango, or BTCL, who send the traffic over either the submarine cable or the vsats.

This means that whoever wants to view these sites is not able to irrespective of who their ISP is.  Blogger. Tropon apeals to the government to end this as he gives proof of the filtering.  The ban was also confirmed by a Bangla newspaper, Prothom Alo.

We at CPB feel that this should end forthwith.
