Following on from our post yesterday regarding the switch to our new website design, I omitted to say that we have also taken the opportunity to move the site to a new host. We were originally using a shared hosting package from a large company. We have now switched to a VPS, virtual private server, slightly more expensive but performance is many times higher that our previous host! You should find the new site much faster as a result!
[Update: 24th July 2010 We are using a virtual server from Linode, so far their service has been exemplary. I can thoroughly recommend them.
