If it's the only network activity the thing does regularly, maybe
the WiFi interface has gone into some sort of sleep mode and the DNS
resolver isn't waiting for it to wake up. If you leave ping running
(eg. "nohup ping -s 1 vps.templar.co.uk &") to keep the interface
active, maybe it will work the first time?

Or if it doesn't change, you could set the IP address for
vps.templar.co.uk in /etc/hosts.
