This requires infrastructure changes which @benbp is working on.

test VerifyCancelCertificateOperation always fail in all job in china cloud

[benbp]

The build has been deleted so I'm not sure what this issue is about. @tzhanl can you be more descriptive in the issue description and title?

[heaths]

That test frequently fails because of timing issues. I've made several changes already to try to combat it, but it's especially problematic. @tzhanl are you saying it's still failing even recently? Changes I have made see this fail much less in AzureCloud, at least.

@heaths it failed in 2/21: https://dev.azure.com/azure-sdk/internal/_build/results?buildId=745075&view=results

@heaths , same failure today https://dev.azure.com/azure-sdk/internal/_build/results?buildId=765075&view=results

[heaths]

Seems Key Vault is taking longer than expected to cancel the operation; however, this is not a priority right now. I'll resolve this as soon as possible.

A similar failure on mac, but not necessarily sovereign-specific:

Error message
System.Threading.Tasks.TaskCanceledException : A task was canceled.
