We're having intermittent issue with ADO repositories. Sometimes when performing Git operations i.e. fetch, etc, we'll receive 429 errors. After waiting for some time or rerunning the process, it will work okay.

    Hi LD Magpantay

    Even if you're using different personal access tokens (PATs) or service principals under the same Azure AD tenant, the rate limiting is typically scoped at the organization or tenant level, not just per token.

    So, using another token under the same tenant won’t bypass throttling if the combined Git traffic from your org is what’s triggering it.

    Hope this helps!

    Hi LD Magpantay

    A 429 error from Azure DevOps Git operations means you're hitting a rate limit or throttling by the Azure DevOps service.

    This is not necessarily a bug, but Azure DevOps way of protecting service availability when too many requests are made in a short time window.

    It resolves after a delay or retry, it's likely a throttling mechanism kicking in to protect the service.
