During maintenance a minor SW library upstep lead to a schema incompatibility problem that impacted +6y old WFD/EM integrations (agent versions 6.8.8, 6.9.35, 6.10.3 and 6.16.29) causing some data to be dropped that was reported by these AP platforms during the course of the incident. This issue started to become visible at 7:20 AM UTC June 15th. As a result, some time series graphs may contain gaps, or some measurements may show a value that is too low for the period of the incident. A workaround was rolled out after which the reporting errors were no longer observed from 9:20 AM UTC June 15th onwards.
