It's OK Sir. Everything is now working fine. I thought may be there is Load Shedding so server is down. When I went to NDLS in June 2014 at that time I encountered frequent Load Shedding. But the Hotels at NDLS are very Good they have Emergency System for 24 hours so won't face any problem.
I also don't know the reason,
In India there are many places where I traveled but my fondness is always with NDLS and it seems to me that I have a long bondage with this...
more... City and it's surroundings(Aapnapan mehsoos hota hai regarding NDLS).
