Xbox gamertag change error message?

I want to change my Xbox gamertag, but when I try to visit the website (https://social.xbox.com/changegamertag), I get the following error message "Error: One or more services have failed. Please try again later." I can enter a gamertag but can't check the availability and do nothing else but on the Xbox live page it says that all services work. Is there a problem with my account or is it Xbox Live and how do I fix it?

Now you can change your gamertag twice for free. If you have already used the 2 times then it is best to go to https://beta.support.xbox.com/contact-us
