Following the February 13, 2018 maintenance window regarding the February 10 Anaplan Maintenance Advisory, duplicate emails (seen below) were sent to announce the successful completion of the window.
We apologize for the extra email notification that you may have received today. While working hard to resolve the above mentioned issue, we had an internal miscommunication that led to the duplicate emails.
Thank you for your understanding. We will continue provide you clear and concise email notifications for future maintenance windows and platform releases.
