I received a reply from GMAC
GMAT Official Practice will be unavailable:
While the fix is deployed Wednesday, November 4th 1:30 AM to 4:00 AM US Eastern Time
During monthly maintenance Wednesday, November 4th, 5:30 PM to 10:00 PM US Eastern Time
We apologize for any inconvenience this may cause, we know taking the site down twice in one day is not ideal, but we want to deploy the fix as soon as possible.
Please save your data and logout before the maintenance window. At the start of the update, any active accounts will be logged out and will need to log back in.
After the fix is deployed, if you are still receiving the error:
