As related in our previous update we are working towards the Meltdown and Spectre mitigations deployment and wanted to provide a brief update.
The mitigations for all published CVEs have now been applied to all the sites
AT-VIE-1. Unlike most cloud providers,
the rollout has been performed in most cases without any impact to your
instances and business.
To be fully protected, you need to apply updates from your OS vendor. Linux distributions come with the appropriate countermeasures. Windows users may follow this guidance in order to apply the required updates.
For existing instances a stop and start from our portal or API is also required to apply the necessary new CPU features.
These mitigations introduced performance regressions for some workload types. We’re confident that further updates from Vendors may improve the situation in the coming months.
