I have a managed dedicated server hosted at Gigenet for more than 3 years. I am very happy with the quality of the service provided by Gigenet.
The server runs a production web system. I hardly remember any downtimes or network problems during the years.
Gigenet's support was very responsive and efficient.
I recommend them as a dedicated hosting provider.
However, their prices are quite high. And when using a 3 year old server, I would expect the monthly charge to be reduced and not remain the same as a the price of a new server.
