Close sincerely apologizes for the interruption of our service. We take the stability of a platform very seriously. Below is an explanation of what happened and how we will prevent another such interruption from occurring.
Between 15:55 UTC and 16:05 UTC on August 1, 2023 Close users may have experienced degraded performance and an elevated error rate when using the Close application or API.
This incident began after a routine deployment of changes to the Close backend. There was a subtle error in a query to the internal metrics service that caused our compute platform to intermittently and erroneously underestimate the true demand for resources after a deployment.
This query to the metrics service has been corrected. Additionally Close has implemented automatic safeguards that will prevent our compute platform from deprovisioning too many resources during peak usage periods.
