We have changed the openEHR.org server DNS resolver settings to point preferentially at Google DNS servers for now, which means all URLs with openEHR.org and subdomains on the website will be served correctly. openEHR.org and subdomains in URLs used elsewhere are not affected (since the problem is limited to the DNS servers on the openEHR.org infrastructure).
Although the underlying problem is still be be fixed, the above should remove any issues functionally.
Thanks for your patience
