I've had a couple of enquiries from customers asking if their PC was OK as they could no longer access METCHECK.COM forecasts for their post codes.
After a little research it appears that Metcheck might be having "people problems". Search GOOGLE for Andrew Bond METCHECK.
If you look at you Metcheck postcode page you will just get an empty page with "Data Temporarily Unavailable", however if you then click on MORE >> to the right of the postcode, all the weather details pop up.
