Engineering teams will continue monitoring the environment, and further updates will be shared as changes are made or once the PoP is restored to normal operation. The status updates are an integral part of proactive monitoring and transparent communication about the status of our cloud services. Imperva investigates and attributes a status to all detected events that may or may not affect availability of the service.
