Hi,
We are using Google Apps for domain validation procedure, so the domain validation server will never be down. So no matter our server is down, you wont have any problem with validation. Have you ever experinced down in google? This is never gona happen. Use a different browser to save your orderId And Username, (chrome, safari or IE) . Template configuration fails to be saved in some browser in some computer, it has nothing to do with server, it is a simple and plain browser issue. Just try a different browser to save your order number and username in the template configuration and it should work out just fine. If not, let me know, i will deeply investigate your individual situation, and please dont worry, we are here to provide you free support until everything is as expected.
Regards,
Support & Development
