MIT OCW YouTube Channel Unaccesible in India?

I was surprised to see find this out today that the MIT-OCW channel on youtube is not allowing access to visitors from India.

This is very unusual as I have been following the channel quite regularly and it seemed to be accessible one week back.

For example, the following link shows a generic `video not available in your country` message.

Has anyone observed similar issue in India or any other nation too ?
