We identified a bug that prevented latency and error rate charts from rendering properly within the context of the Service Directory's Key Operations.
The bug has been fixed and deployed to production. So, going forward, Key Operations will return to normal and the visible gaps will roll out completely in 8 days.
Until then, the Key Operations charts may show gaps prior to 5/25.
The underlying data is still accessible, so if there is something needed for a particular time frame please reach out to support@lightstep.com.
