Our servers netboot onto an NFS root file system. This approach has a
number of benefits over using local flash storage on the Pi.
storage avoids the reliability and performance issues associated with
flash storage, and gives us greater flexibility over the size of storage
Use of netboot also makes it impossible to “brick” the
server: if you make the server unbootable, we can recover it by booting
to a rescue image.
Servers come with IPv6 connectivity. We expose SSH over IPv4 via a
gateway server, and the service includes access to our IPv4-to-v6
proxy, allowing you to host websites on an IPv6-only server.
Servers are currently being provisioned in the Meridian Gate data centre
in London Docklands. Servers are connected at 100Mbps to a switch on our
core network with direct access via our fibre ring to multiple 10GBps
uplinks, including the London Internet Exchange (LINX).
