Stable Server Located in Europe?
 

My current host started to make me nervous because of bad customer support and downtime.
Most of my clients are located in Europe. Stable server with 500 gbs of space, 16 gbs of RAM and 5000 gbs of bandwidth.
GTHost.com was recommended to me as a good option. What can you say about them? need feedbacks. Also any alternatives?

Thanks in advance.

As an alternative, give ZakServers.com bitcoin dedicated servers a try.
They were extremely patient as I cluelessly asked for various ports to be opened to allow extra functionality on one of my sites.
