I don't know about Steam, but I know Apple must use Google Cloud: https://www.apple.com/support/systemstatus/

Less than 1% of users are affected

Is there any reason to presume these statuses are correlated?

Apple's issue is

> Users may be experiencing slower than normal performance with this service.

I'm just assuming they are because it's been previously reported that Apple uses GCP (and also AWS).

Could be the only users who were affected were ones caught right in the failover between redundant clouds

Guess they don't eat their own dog food; no racks of proprietary Apple servers anywhere (unless they somehow run Darwin images in Google Cloud)

Can't tell if you know the answer to your own question and just can't talk about it due to NDA...

Apple runs Linux on the vast majority of the servers behind their cloud offerings.

No issues for me. Maybe they have a failover mechanism?

yeah, maybe it was coincidence. seems to be back up for me as well: https://steamstat.us
