Googlebot can't access your site

Hello there

I have two sites using the shop theme , http://www.abal.ie , http://www.tablets.ie both are giving errors in google webmaster tools
Both errors are Googlebot can’t access your site, When I go to fetch as google I am getting the error Temporarily unreachable. Does anyone know why I could be getting this error ?

Both sites are on my own server, I have other sites on the server that google can fetch with no errors it just seems to be the two sites I’m using the premiumpress shop theme with that is causing me the problems
