Issue is impacting South East Asia and South East Australia regions as of 5/24 2018 at 19:45 UTC.

Root cause has been isolated to a backend availability issue which was impacting queries. The backend service is in process of being restored. Some customers may experience delayed queries in these regions and we estimate 1 hour before the issue is fully addressed.

• Work Around: None
• Next Update: Before 05/24 23:30 UTC
