I can verify that it's true. Twitter does not open using Reliance Broadband. I don't use twitter so it never really bothered me but it's interesting to see that twitter is the only website that I've come across which doesn't open up on Reliance.
If, once in a blue moon, I need to use twitter, I access it using a proxy server. I use the addon Anonymox on firefox for this purpose as it automatically finds and connects you through a working proxy without you having to manually pick one. Through the proxy, twitter opens just fine. Wonder if Twitter and Reliance have some war going on
