Cloud TPU Service Activation is impacted.

Summary: Cloud TPU Service Activation is impacted. Description: We are investigating issues where customers using TPUs through Vertex AI Service or Cloud TPU Service/API directly may be experiencing API activation failures. This can happen for new customers or existing customers who disable and reactivate the TPU Service beginning on Wednesday, 2024-08-07 12:00 US/Pacific. Our engineering team has rolled out a mitigation and is progressing as expected. We will provide an update by Wednesday, 2024-08-07 19:00 US/Pacific with current details. We apologize to all who are affected by the disruption. Diagnosis: Impacted customers would not be able to enable Cloud TPU APIs in their projects and would encounter an error message that states, e.g. "Failed to upload model. Contact Vertex AI." We continue to investigate impact to other Google Cloud Services and products. Workaround: None at this time.
