There's fairly clearly an global Internet filtering trend afoot, with countries like the UK and the Netherlands banning access to the Pirate Bay,
blissfully unaware that the filters don't work -- and in fact only deliver free advertising to the website. India appears to be taking things one step further,
ordering ISPs to ban the Pirate Bay as well as video-sharing service Vimeo. Vimeo of course is a haven for non-pirated legitimate independent work, so the ban appears to be suffering from a bad case of blind ambition.
India hasn't officially announced the move, ISP users are just greeted with the following screen if they try to access restricted websites:

As with other such filters, these are usually ISP DNS based, meaning that users simply have to use a VPN or switch to an alternative DNS provider to continue accessing the content.
