As we have noted, we are engaged in a full-scale response. We continue to communicate directly with customers if we need to take actions that would impact their environments.

While we can’t currently offer a timeline when full mitigation and remediation will be complete, we will update this blog post when we have relevant new information to share. We understand this lack of information can be frustrating. However, we are providing updates on how mitigation efforts are affecting specific services on the Rackspace Support Network.

On Jan. 3, 2018, Rackspace was made aware of a set of vulnerabilities affecting certain Intel, AMD and ARM processors.  

We are addressing the issue as vendor patches are released and workarounds become available.

Further details about the security vulnerabilities can be found here. The U.S. Computer Emergency Readiness Team and the National Counterintelligence and Security Center have released the following:   

At Rackspace, we’re focused on ensuring our solutions best support our customers’ environments. We’re implementing a plan of action and proactively investigating solutions to remedy this issue.

While there is currently no single fix for the vulnerabilities, a number of vendors have released suggested mitigations and remediation(s). As these are released, we’ll assess, test, coordinate and deploy accordingly across our environment. We will communicate to affected customers if actions that would impact their environments are required. 

This is a complex and evolving situation. Our first priority is to ensure our customers’ environments are protected, and we’ll do that in the least impactful manner possible.
