Yes, yes we are.

time to spread resources across clouds? or would that be too expensive?

this one appears to be just global LBs, so a load balancer in AWS/Azure that hits the actual backends over a VPN or something would have worked, but that's just this case

Even Google Cloud's non-global load balancers, which live within a single region, wouldn't have hit this particular outage.

jep we had non-global lb's in europe-west-3 and i could not sense any outage.
