Hello Marek Kembrowski,
Thanks for raising this question in Q&A forum.
You're experiencing a known regional issue. Sweden Central has had ongoing Azure OpenAI/AI Services outages since January 27, 2026, with continued problems reported on January 28-29.
What's Happening
The outage affected deployment metadata and caused resources to enter inconsistent states. Your "Another operation is being performed" error and 404s on existing deployments are direct symptoms of this platform issue.
Immediate Actions
Check Service Health: Azure Portal → Service Health → Resource Health for your specific resource
- Wait 30-60 minutes before retrying deployments - the backend may still be recovering
Verify deployments via CLI:
bash
az cognitiveservices account deployment list --name <account-name> --resource-group <rg-name>
- Open an Azure Support ticket immediately - given the ongoing regional issues and your inability to switch regions, Microsoft likely needs to manually restore your resource
This is a platform-level issue affecting multiple users in Sweden Central, not something you caused.
If this helps accept the answer.
Best Regards,
Jerald Felix
