How to get low latency on Azure central/south India server.

Question

Have been facing high latency on the GPT-4.1-mini and other models, with every response exceeding 1000ms.

Answer 1

Hi Aditya Purohit,

Following up with an update from engineering.

Based on our investigation, the elevated latency observed on GPT‑4.1‑mini and related models in the Central/South India region was due to a service-side issue, which is being tracked under INC 747008667.

Issue:

Requests were experiencing higher-than-expected end‑to‑end latency (>1000 ms) due to a backend service regression affecting request handling and routing in the region.

Resolution:

Engineering has applied a service-side mitigation to address the latency issue. The fix restores normal request handling behavior and improves response times. No configuration or code changes are required on the customer side. The improvements will be reflected automatically as the fix completes rollout.

If you are still seeing higher latency after this update, please share:

Deployment name

Region

Approximate request timestamps

This will help us validate that traffic is hitting the updated path.

If you have any remaining questions or additional details to share, feel free to let us know. We’ll be glad to provide further clarification or guidance.
