We support both Operating System virtualisation (using OpenVZ) and Native virtualisation (using KVM, including VIRTIO for increased disk performance.)

We provide both IPv4 and IPv6 addressing.

VPS Advice - Buying Guidelines

When buying or leasing a VPS you are in effect buying these components:-

• Bandwith: Is there enough for your needs and is the device located physically close to your users?  If there is a large physical distance (many cheap providers are located in the US) things will be less responsive.  Depending on what you're hosting this could matter, or it might not.
  • Our servers are in a Tier4 data center only 2ms from the London INternet eXchange point (LINX) and London Network Access Point (LONAP) with more than 20Gbps redundant access.
• RAM: A VPS can show that it has 512MB of memory, but this might not be instantly available when your VPS needs it.  Much like airlines oversell plane tickets a VPS host can over sell RAM by swapping your applications to disk.  This has the effect that things could be up to 100X slower until some RAM is freed up and the your application is swapped back in.
  • Our servers have more than enough RAM, and in fact do not even have swap memory allocated.
• CPU: This is the most easily over sold component since in most environments it is the least used.  The key is to ensure that computational tasks are responsive - perhaps log the time it takes to run certain key functions to ensure you're not on an overloaded host.
  • We operate Dual Quad core Intel Xeon servers and would be happy to show CPU utilisation graphs to prove we have the reasouces to accommodate you.
• Hard drives: Hard drives start writing data on the outer edge of their platters, data access here is almost 1.5X faster than toward the inside.
  • We use RAID1+0 (for best redundancy and best performance) and ensure that when individual drives are more 50% used we move data onto another drive.
