Several cloud vendors began responding to the chip kernel vulnerability  that has the industry reeling today. Each Infrastructure as a Service vendor clearly has a stake here because each one is selling CPU cycles on their platforms.

TechCrunch sent a request for comment to six major cloud vendors including AWS, Microsoft, Google, IBM, Rackspace and DigitalOcean. At the time of publication, we had heard directly from three of the companies: Microsoft, Rackspace and DigitalOcean. In the case of Google and AWS, we learned their response indirectly through published blog posts. We have not yet heard from  IBM.
