   We have identified a failure of a cloud provider's availability zone as the source of the issue affecting CSE APIs, CSE UI, Data Indexing, Metrics Alerting, Metrics Collection and Tracing Collection. The symptoms are: latency in processing and displaying log data, latency in processing and displaying metrics data, latency in processing and displaying tracing data, UI slowness, latency or errors communicating with API. We are working on a fix for the problem and switching traffic off of the affected infrastructure.
