Dear Customer,
We are writing to inform you we will be performing a maintenance work (failover) on our platform. 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. On this first stage our primary site will be switched to secondary and our DR site will be acting as primary. This should not cause any issue and all services will be working normally while the failover test is running (apart from the 20 minutes downtime highlighted above). We will leave the system running on disaster recovery (DR) site for about 3 days. Once the failover test is complete, we will switch back to the previous configuration, this being the failback maintenance notification coming out shortly.
Maintenance start time: 25/09/2020 - 00:00 am UTC
Maintenance end time: 25/09/2020 - 05:00 am UTC
Impact: All services during a maximum of 20 min. 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
