Pondicherry is not a big city. It is more of a tourist spot, and a place wehre politicians fight for their superiority within their 1 KM zones in which they would be elected.

Untill a few months ago, the connection at my home used to give problems every once in a while, and I used to get heavy bills for the usage though I doubt that I have used it much in those days, but right now, with the unlimited connections both at home and office, there is hardly any downtime.

Server farms are typically co-located with the network switches and/or routers which enable communication between the different parts of the cluster and the users of the cluster. Server farms are commonly used for cluster computing. Many modern supercomputers comprise giant server farms of high-speed processors connected by either Gigabit Ethernet or custom interconnects such as Infiniband or Myrinet. Another common use of server farms is for web hosting, which are sometimes referred to as web farms. Server farms are increasingly being used instead of or in addition to mainframe computers by large enterprises, although server farms do not as yet reach the same reliability levels as mainframes. Because of the sheer number of computers in large server farms, the failure of individual machines is a commonplace event, and the management of large server Continue Reading
