So it turns out there is unfortunately another major bug within Intel's CPU architecture, that this time specifically affects multi-tennant environments. Bad news for any cloud provider! Fortunately we have been on the case and have put a patch live already. However we also recommend that everyone else does the same. We have a good blog post explaining a bit more here: https://www.civo.com/blog/intel-s-latest-security-vulnerability-our-steps-and-yours If anyone wants to ask any questions or just have a rant at Intel (I did as they made me do the late night change ;) ) Feel free to share your thoughts about it here.
