Here is a copy of an email I received:
Dear Customer;
As an Enterprise Flexible program user, we wish to ensure that you receive the information you need in a timely manner.
As part of the initiative to upgrade and enhance our application infrastructure, we will need to take down certain enterprise applications. The scheduled downtime is set to begin on June 2 and last until June 8. This downtime will be used to conduct a series of master data conversions which are prerequisite activities for the system upgrade that will be implemented in November. During this time, the Enterprise Flexible web site will be unavailable.
Should you urgently need a License Key during this downtime, feel free to contact your contract advisor.
Best regards,
