We have been made aware of the Microarchitectural Data Sampling (MDS) vulnerability (also referred to as ZombieLoad) existing in Intel CPUs. We're working with our cloud providers on patching these as soon as possible.
These mostly affect our web services and Cast infrastructure. Once patches are released they will be applied between 12 and 4 AM GMT time. They should not cause downtime but there might be a small interruption or performance degradation while these are being applied.
