Cisco Meraki, a cloud-based application for centrally managing a company’s WiFi network settings, server routing information, CCTV systems, and other security settings. Cisco engineers working on the Meraki service on August 3 uploaded a malformed configuration file that applied an erroneous policy to the service’s North American storage system, causing some data uploaded before 11:20 AM Pacific time to be deleted. This means that many companies will have to re-configure their Meraki accounts. It is unclear how many of these clients were affected as Cisco declined to provide exact numbers.
