Question

Do requests to Graph API resulting in the 503 and 504 responses described here https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview count towards the throttling limit described here https://learn.microsoft.com/en-us/graph/throttling-limits?

Hi @Peter

Requests to the Microsoft Graph API that result in 503 (Service Unavailable) and 504 (Gateway Timeout) responses do not count towards the throttling limit. Throttling is specifically triggered by exceeding the request limits, which typically result in a 429 (Too Many Requests) response.

If you encounter 503 or 504 errors, it usually indicates temporary server issues or network problems rather than throttling. It’s always a good practice to implement retry logic with exponential backoff to handle these types of errors gracefully.
