Incident Report

Summary AI Generated

Elastic Cloud experienced elevated error rates for the `microsoft-multilingual-e5-large` embedding model over approximately 4 days, causing search embedding requests to fail due to upstream provider issues. The model was ultimately retired from the Elastic Inference Service, with all requests to it now returning an error. Customers requiring this model must configure a custom inference endpoint using their own API key, with guidance available in the [Elastic inference documentation](https://www.elastic.co/docs/api/doc/elasticsearch/group/endpoint-inference).
