With the launch of our new Paris and Manchester locations (with 5 more coming soon), we are doing some free nodes for new AND existing customers. All you have to do is login to the control panel and create a new VPS.
Make sure you select "Promo Nodes" as the node type.
Select the Manchester or Paris clouds as the clouds to build on and you're done.
For new customers we allow one promo node. For existing customers the number is limited to 20% of your nodes, or one node, whichever is the greater amount.
These nodes are free for 30 days and then become chargeable at our normal rates. Any questions please drop firstname.lastname@example.org a line and we will be happy to help out.
