  5. resolved

    Between 19:24 UTC on 22 July and 01:50 UTC on 23 July, customers using the gen3 preview machine (Linux VM) resource classes experienced delays and, in some cases, jobs failing to start. We have removed the gen3 resource classes while we address stability issues affecting them. Unfortunately, workflows that we were unable to provision compute capacity for during this period were cancelled. Affected customers should change their resource class from gen3 to gen2 and rerun those workflows. We thank you for your patience while our team worked to resolve this.
