Some customers in Pod 4 reporting green screens. We are working to confirm scope, and will tweet again with any specific developments.
Customers in Pod 4 reported green screens and access issues with their accounts. Root cause investigation, including checking all network metrics, alarms, and dashboards, revealed no issue within our network to cause this incident. Based on traceroutes from one customer, it was discovered that they were traversing an ISP's network. Disabling that ISP circuit in the West Coast datacenter, which routed traffic through a different circuit, resolved the issue. A case was opened with the ISP to investigate; however they have so far reported no scheduled maintenance and no latency, loss, or over-utilization on their circuits during the timeframe of the event. We're investigating additional monitoring to help track down this kind of issue in the future.
