Customers who run their Web applications on Google App Engine were forced idle Thursday by a series of issues involving "elevated Datastore latency and error-rates, as well as elevated serving error-rates," according to a Google employee posting in the Google App Engine Downtime Notify group spotted by TechCrunch. A Google representative acknowledged the downtime and apologized for the outage.

"Today at 8 am PT datastore access for App Engine applications was affected due to a cluster-wide issue. The team identified and fixed the underlying problem that caused the outage and service has now been restored to all applications. We apologize for the inconvenience and encourage anyone having technical difficulty to visit theSystem Status Dashboard or the Downtime Notify Group, which are both linked from the Google App Engine Community site."
