Our logs show the incident started on 12/07, 12:00 UTC and that during the ~11 days and 18 hours that it took to resolve the issue some customers in South East Australia region would have experienced intermittent failure notifications while attempting to query data from the Azure and OMS Portals.

• Root Cause: The failure was due to issue with one of our dependent backend service.

Update: Wednesday, 19 December 2018 01:01 UTC

Root cause has been isolated to unexpected query load which was impacting data access for few SEAU region customers only. To address this issue we applied a mitigation to see if it helps. We are monitoring the scenario in this region to see if everything is working as expected. Some SEAU customers may experience intermittent data access from Azure and OMS portal and we estimate few hours before all data access issues for SEAU customers are addressed.

• Work Around: NA
• Next Update: Before 12/19 07:30 UTC
