Intermittent inference_service_unavailable_error affecting gpt-realtime-1.5 (Azure OpenAI Realtime)
A Microsoft Q&A thread (question posted 2026-04-01, with activity on 2026-04-03) documents intermittent inference_service_unavailable_error failures affecting the gpt-realtime-1.5 model via the Azure OpenAI Realtime WebSocket API in at least the Sweden Central region. Users report repeated inference_service_unavailable_error and realtime session failures; Microsoft staff have commented in the thread. This appears to be a user-visible availability problem rather than a resolved routine support question.
