Impacted Cloud Regions & Services: azure:production:eastus2 and aws:us-west-2

User Experience: For organizations hosted in the affected regions (aws:us-west-2 and azure:production:eastus2), scheduled materializations and scheduled exports did not run for the duration of the incident. Exports and materializations have since returned to normal operation. Organizations with a high volume of scheduled exports may experience some delayed processing as queued jobs catch up.
