The servers are racked up and we’re busily getting them prepared to go live. We’re planning to effect a very smooth changeover – the load balancer will be using HAProxy which means we can switch the DNS over in advance but proxy the site from the old server until we are ready. At that point, we take the site down, transfer a database snapsnot, reconfigure HAProxy to use the new servers and bring it back up.

More news as it happens!
