Azure AI Forms Recognizer Service is failing

Question

The FormRecognizer service in East US is failing. We have code that has been running with no changes for over a year and right now each call is failing. The second line of code below is what is throwing the error shown below.

Please do not ask for more details about what we are doing. This has been running for over a year with no changes so something is failing on Microsoft's end. Please escalate this to the proper team immediately. It has been happening since at least 4:24 EST this afternoon, over 3 hours now. Why isn't Microsoft's team aware of this? Nothing shows up on the service health section.

DocumentAnalysisClient client = new DocumentAnalysisClient(new Uri(AISettings.DataEntryAIEndpoint), credential);
.....

AnalyzeDocumentOperation operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, model_name, stream);  
AnalyzeResult result = operation.Value;
