Looks like another myopenid.com failure. I think their server is working again now though. Try to log in and then go to "my account" -> "logins" in the menu and add an OpenID identity from a more stable provider. myopenid.com is unfortunately not reliable anymore.
It appears the myopenid.com website is working though...
In now, finally
I have added another account as advised. Thanks for your assistance
