My first review here, but I think @jarland deserves it.
I have been using a Catalyst Host VPS since August when they launched. Specifically I have the VPS at FDC Denver, a custom plan with 250 mbps unmetred and 256 MB of memory.
Let me be clear: I am using most of the resources allocated to me, including 30 TB of bandwith each month and a full core of a relatively old Xeon L5520, here you have some stats. I am not abusing the node but my container hasn't been sitting idle during this time.
Uptime has been great, ticket response times always low and both @jarland and Ryan are very friendly and they genuinely care about their customers. They may not have their own ASN and are new providing VPS hosting, but if you are interested on any of their high bandwidth or new storage plans, you can't go wrong with them. You will not be at the best network of the world with FDC Denver but the price it's ridiculous if you need tons of bandwidth. I don't know any other low end provider like them for bulk bandwidth.
