A number of serious security vulnerabilities affecting multiple CPU architectures were recently disclosed by Google's Project Zero team as outlined in our blog post[1]. In order to address the disclosed vulnerabilities, the physical hardware on which resides will need to undergo maintenance. This is the first of several separate maintenances that will be necessary to fully mitigate these vulnerabilities. This maintenance specifically patches the Meltdown vulnerability; the Spectre vulnerability will be addressed in a future maintenance cycle. We will inform you of these maintenance cycles via additional tickets.
