nope they do not have the best pings, the best pings we get on are on Kolkata server.Those servers might have low ping. When I had a gaming IP, Railtel kolkata server wouldn't connect, so by default, other servers with similar ping(<10ms) were being selected and I had full speeds during tests.
What is your IP range?Current pings for railtel servers on my network
BBSR - 17 ms (getting full speed)
Kolkata - 11 ms (not showing full speed for me.. hovering around 15-16 Mbps)
Also still the ISP name is showing blank instead of raitel. And default server selected are some unknown ones (Bhusaval/Yavatmal was getting selected for me). Earlier by default the server showed railtel kolkata or hyderabad for past few weeks.
