Hi,I have been stuck with sify for years, and finally plan to make a switch as TATA has become available in my area. But I have heard some negative things about the TATA/VSNL connection as well, so what all should I find out before making the plunge? The provider only said that they have a fiber optic connection, and nothing more, and as this is a university area, there aren't too many people who have taken the connection.Also, I haven't decided between the 128UL and the 2mbs NU connection. A few questions about the NU plan1. Is it still available?2. How is the time logged in during the day computed? Do we need to connect using pppoe? If one logs in for 15 minutes at a time during daylight, would one be charged for the whole hour?3. Is their system reliable? Could one be charged for the entire night due to some mistake?4. Effectively how many day hours/month does one get with the plan?Basically, I am quite eager to quit the sify wagon, but am not sure if I would be jumping from pan to fire, as the saying goes. Any help would be greatly appreciated
