Hi Sam,
Yes, sometimes the website has trouble.
The problem is Wordpress is a bit of a beast and it's only a small entry level VPS (free).
To mitigate this I've tweaked the HTTPD to use less memory and the Wordpress install to cache (almost) everything.
It's not enough.
What I plan on doing as a quick fix is moving the DNS over to CloudFlare so if the server does drop off, the website will be served from the cache, however the domain is not controlled by me, so I need to get that sorted with Richard.
I've restarted the HTTPD which should make the site respond for now.
Ta.
