BSNL cuts some customers over to some other network and stays silent. Some folks with the 5X.XX.. IP addresses would have encountered PPPoE auth failure unexpectedly with the ‘usage’ page telling that userid is suspended. They might have moved it to the 117.XX. network where the user id is of the form xx (xx being “ln” for Indiranagar, Bangalore) and password is just “password”. I wonder how they were expecting to notify the users about this change since they dont have any ACS or remote management stuff setup.
