When the leased line is down dial-up is used to do the mail transfer. Getting from Bombay to Bangalore seems to be better as IISc seems to have developed quite an impressive setup. I think the 64K link also funtions there. Usually very reliable and efficient. NCST is the center.
DoE is linked via Bombay.
They provide SLIP, UUCP and user accounts. This is the list that I can actually see on the internet and can get to also. Howver, all of these are notm fully functional and ome of them are basically just there for name sake. It isn't even all of the government organizations but limited ones. Basically, the unreliable connections were because of problems on the leased line between Bombay and Delhi.
