Rackspace has admitted a ransomware infection was to blame for the days-long email outage that disrupted services for customers.

In its most recent update, posted at 0826 Eastern Time on Tuesday, Rackspace said it has now "Determined this suspicious activity was the result of a ransomware incident," and has hired a "Leading cyber defense firm to investigate."

Rackspace reiterated that the intrusion was isolated to its hosted Exchange businesses, and noted no impact to Rackspace Email and its other products.

Rackspace declined to answer The Register's questions about how many customers were affected, who is responsible for the ransomware attack, how they breached the network, or the payment demanded, among others.

The spokesperson did clarify a point from a press release issued today about the ransomware attack that indicated the incident may result in a loss of revenue for its hosted Exchange biz, which Rackspace said brings in about $30 million annually.
