Hello,
We are writing to inform you we will be performing maintenance work on Smart Messaging Tailored: failover to the disaster recovery (DR) site. We expect the maintenance activity will result in a maximum downtime of 20 minutes. See the summary below for further details.
Description: we are performing a failover test on our HADR infrastructure. After running the system on the DR site for 3 days and once the failover test is complete, we will switch back to the previous configuration (failback). On this second stage our primary site will be switched back to Primary and our DR site will be switched to DR again. This failback should cause a maximum disruption of services for 20 minutes.
Maintenance start time: 22/10/2021 - 00:30 am UTC
Maintenance end time: 22/10/2021 - 06:30 am UTC
Impact: All services during a maximum of 20 minutes. While inbound messages will be queued by the operator, outbound messages will not be processed and will result in failure during downtime.
We apologise for any inconvenience this may cause and will email you at the beginning and end of the maintenance period. If you have any questions or concerns, please contact our support team at support@tailored.bt.com
Best wishes,
Smart Messaging Tailored Team
