WCMS website content may have been lost – September 6

What is happening? Information added to WCMS websites on September 4 and September 5 may be lost. 

Why did this happen? Due to the MC power outage, databases in the MC data centre were shut down, leaving only EC2 databases available for the WCMS during the outage. Once the power outage was complete and services were beginning to be restored, a misconfiguration resulted in data being written to the databases that were previously turned off before replication was restored. When replication was restored this data was lost.
