Google said they've finished patching, and it was all done before the bug became public.
That means the people who have the best information about mitigating this issue have a fix that apparently has minimal performance impacts on their cloud workloads, and I suspect their cloud customer SLO's would be taking a shitkicking if that weren't actually true.

- bobdole1234 9y agoMore likely, Google made their own mitigations, that they're keeping for their own competitive advantage. They've had a lot more time with the problem than anyone else has, and billions of dollars to gain by solving it better than anyone else. If they had a 15-30% loss of performance in their 3+GW of infrastructure, it would almost certainly cause a significant dip in their quarterly results, and they would want to warn the markets about that well in advance to soften the blow.
