uptime only 66%
night 11 pm daily gets disconnected
no legal dynamic ip, spoofed ip created by sify itelf. so you can not use some ftp protocols and voip protocols. I have never seen such a intelligent company cheating the people and telling they will give a static ip and providing a spoofed static ip that you can not ping from the internet. We downgraded from 512kbits to 128 kbits after we got cheated that they are giving static ip address
very slow
no technical staff only layman
no windows dialer . sify dialer with trozan suspected
if we put some download and go home they disconnect the net every hour to limit users using automatic downloads and auto logins so in the morning nothing will be downloaded so you can never use night free option
never buy any internet service with out windows compatible dialers
sify has its own dialer
the connection is disconnected every 2 seconds so users can not use voip phones or skype so you can not voice chat or video chat

so sify is meaningless
