In the East Asia region, all Azure AI models, including features such as aiModels.openai.ada.1, aiModels.openai.babbage.1, aiModels.openai.curie.1, aiModels.openai.davinci.1, and aiModels.openai.gpt-4o-audio-preview.2024-12-17, have stopped being available. In the East US region, multiple VM SKUs, including basic and standard models, have either become absent or unavailable, affecting a wide range of features.
2 new183 regressions11,895 parked
Compared with the 2026-06-28 snapshot, the 2026-06-29 scan recorded 2 new listings, 183 regressions, and 11,895 parked unknown transitions.
Representative changes: ada model from OpenAI (version 1) was no longer listed in eastasia; babbage model from OpenAI (version 1) was no longer listed in eastasia; curie model from OpenAI (version 1) was no longer listed in eastasia.
What this means: Review the 183 regressions against existing regional targets and fallbacks first; treat the 2 new listings as options to validate. These are read-only catalog/list signals, not quota, capacity, or deployment results. Zero new delistings does not establish recovery of earlier missing listings.
7-day context (2026-06-23 to 2026-06-29): across 7 recorded scans, there were 1,723 new listings and 1,046 regressions. New listings led on 4 scans; regressions led on 3.
