sharepoint – Reduced speed for Microsoft Graph API

Over the past two days the speed for retrieval of data through the Microsoft Graph API has diminished tremendously. Downloads that used to take above 5 to 10 seconds have now increased to 30 seconds to 1 minute.

If you could please help me out to resolve the issue, it would be of great help. Users are accessing the API mainly from Australia.

Thanks and Regards,
Noel
