End: Thursday, 08/29/2019 6:00 AM central

Impact:

We are not expecting any impact for our clients.

Reason:

After replacing a defective hard disk drive last night, the storage array exceeded the maintenance window we scheduled to complete the resynchronization process. We decided to delay replacing the faulty power supply until the storage is back in a fully fault-tolerant state.

Conclusion:

This is the last maintenance for the SAN and will put it back to a redundant configuration.
