It happened earlier as well. In IPL, i activated channel on daily basis and never faced this kind of issues. Faced during NZ series.
This time, I have not activated any star pack and found another medium which I felt more profitable to watch regional contents and movies also in HD itself so got out of this issue. But this is happening purely because of huge subscriber base. As an IT guy, it is time for TS to add more servers at least during critical and more demanding time..
