I am pretty sure Google Ads, search core business, Gmail (workspace), YouTube, and their main web properties are not affected. Does that mean they use a different network/IDC for Google properties? Maybe all of their web properties are designed with multiple HA zones. I don't know.

Kind of interesting to speculate what kind of traffic needs to transit and what doesn't. It would be a major efficiency failure if the services you mentioned needed to transit the atlantic for any reason. "Maybe all of their web properties are designed with multiple HA zones." I don't think it's physically possible that Google could do what it does without a comprehensive edge network.

  I would expect mail delivery flows cross the entire network on average because the mail arrives from places that are in no way related to where the user account is homed.

  I did capacity planning for a large user facing service more than a decade ago. Not only we had global N+2 redundancy (we could still serve peak traffic if we lost the two largest clusters worldwide), but I also made sure we had at least N+1 per "continent". That's how I managed to get resources for us in the infamous, reserved and now long gone Budapest cluster(s), whose only other tenant was Gmail.

What's an HA zone?

  High Availability. A service with (hopefully) a lot of 9s in its percent uptime.

Remember when Google was a search engine that tried to find an ethical way to do ads to support the search engine? Those were fun times on the web, when the alternative was curated lists on Yahoo or... whatever the hell Ask Jeeves was aside from a collection of Easter Eggs directed at rude middle schoolers.

I used to work at YouTube so can speak to that; I assume the other high-value properties are similar. YouTube runs many geographically distributed datacenters and can each more-or-less independently serve user requests; there's also sufficient redundancy that a full DC can go down and the rest are able to carry the redirected load. When a link goes down like today it's often not user visible as most requests are already served at least from within the same continent. If a whole data center goes down, users might experience higher latency from longer round-trips and colder caches because their traffic is being routed to a DC further away that now has more diverse traffic, but they also won't experience an outage. This stuff was fun to work on. :)

  Thanks for the comment! Always nice to hear snippets about the resilience of these types of systems
