Cisco has admitted to losing customer data during a configuration change its enginners applied to its Meraki cloud managed IT service. From a report: Specific data uploaded to Cisco Meraki before 11:20 am PT last Thursday was deleted after engineers created an erroneous policy in a configuration change to its US object storage service, Cisco admitted on Friday. The company did say that the issue has been fixed, and while the error will not affect network operations in most cases, it admitted the faulty policy "but will be an inconvenience as some of your data may have been lost." Cisco hasn't said how many of its 140,000+ Meraki customers have been affected. The deleted data includes custom floor plans, logos, enterprise apps and voicemail greetings found on users' dashboard, systems manager and phones. The engineering team was working over the weekend to find out whether the data can be recovered and potentially build tools so that customers can find out what data has been lost.
