Experiencing Data Latency for Log Analytics in East US 2 region - 09/04 - Mitigating

Update: Saturday, 04 September 2021 18:38 UTC

Root cause has been isolated to the failure of a back end compute cluster which caused incoming data to queue up and not be processed. To address this issue we restarted the cluster.  Ingestion is now working as expected and the backlog of data is now draining. However, because there is a large amount of backlogged data, some customers will continue to experience data latency and incorrect alert activation. We estimate several hours before all the backlogged data has been ingested.
