hosting service

Hello guys, Can anyone share you information regards VPS hosting providers with night ship can be much attractive, please suggest a good provider for this. Also, please suggest should I consider a linux server for this ?

I have a dedicated server that used 2 years, if comparing with servers at this time then its specifications is not good because it is used pretty long time, should I buy a new server and move websites to new server to have better configs at same price?

Did you check reviews, specs or something else before before purchasing web hosting service from a web hosting provider? or you just buy their service if they fit your requirements?

As title, what to do if your hosting is becoming bad? in first months your hosting service is good but its becoming bad because your hosting provider is changing rules or suspend your service without any reasons? I moved 4 times to new hosting provider after faced same problem. What bout you...
