I'm also getting error messages when logging into my Altitude account:
Due to technical difficulties we are unable to display the information on My Dashboard. Please also note that if you are trying to choose your Select Privileges, this function is also temporarily unavailable.
We thank you for your patience while we fix this issue and apologize for any inconvenience this may cause.
I guess the two are related, time will probably get this fixed, will try again later this week.
