Problem Description

HEAnet require a window to troubleshoot issues that occurred during a planned migration of hosted services within the Parkwest Datacenter in December 2018.

Problem Effects

During this migration a small number of client services had DNS issues that interrupted normal behaviour. Following exhaustive review of the day’s events a root cause for the outage has not been identified so this troubleshooting window has been agreed, during which it is expected the same client services will be affected. All clients who will be directly impacted by this troubleshooting have been informed HEAnet have taken every precaution to recreate these events in a controlled manner. Rollback plans are in place in the unlikely event of other, unexpected disruptions to any other client services.
