This affected us starting at 4:57am US/Pacific with a significant drop in traffic through the HTTPS Global Load Balancer across all regions and Pub/Sub 502 errors but there was nothing on the status page for another 45 minutes. Things returned to normal by 5:05am from what I can tell.

Yup we saw the exact same symptoms with some GCLBs getting 100% 502 ( our upstream QPS graph looks scary with 5 mins of 0 QPS )
