Gemini disaster recovery test 2023

Every year we carry out a disaster recovery test on Gemini

As part of this exercise, we confirm that production Gemini services can be migrated to a secondary data centre location. This ensures that Gemini can continue to operate if we encounter a catastrophic failure with the primary data centre.

This year’s test will take place on Saturday 3 and Sunday 4 June

Activities will start in the standard Gemini maintenance windows. If we encounter any issues extended system outages may be required.

Failover from the primary site to the secondary site - Saturday 3 June

Failback from the secondary site to the primary site - Sunday 4 June
