Active - Failures while accessing Azure OpenAI Service

Impact Statement: Starting at approximately 00:01 UTC on 13 July 2024, a subset of customers across multiple regions using the Azure OpenAI service began experiencing errors when calling the Azure OpenAI endpoints and may have issues accessing their resources for the duration of this impact. Current Status: During a routine cleanup operation, we believe that some dependent backend components became unavailable, which led to the aforementioned issues. This was believed to be transient, as initially, this only affected a small percentage of customers, however it soon increased to multiple regions. We have stopped the cleanup operation to avoid further impact, while we continue to work on our recovery efforts.These efforts are ongoing across all impacted regions, which are seeing partial service restoration. Customers in these regions may start noticing improvements. Retries may be successful as the mitigation progresses across the different affected regions. Initially, this issue was communicated via the public Azure Status page, as the full impact was not adequately determined. Now that the root cause has been determined, and the impact is no longer increasing, all further updates will be communicated via our standard communications to impacted customers in Azure Service Health.
