A insight on Crysis 2 demo shut down

[{FWE}Ontime-Adm]

Please all take in consideration the official Crysis 2 Demo shutdown!!  ( 3/13/2011 )  why can some still play and some not play random kicks I cannot play but my friend can,
The demo server cannot just shut down and disappear,there are networks involved which needs to be shutdown slowly,these servers are connected to other game servers,and extreme caution needs to be taken and shut downs will affect other servers (Games) will be affected by this,keep in mind this is just a thought.
