Luckily GCP load balancers and Pub/Sub we're generally unaffected, at least for us, which are the 2 products we depend on the most. Messages piled up in Pub/Sub while other GCP products were down but that was it. We did uncover a few spots where we had a GCP product dependency in the critical path that didn't need to be (the actual usage is optional but we don't ignore the error).

In most industries there isn't an expectation that providers are multi-cloud because these multi-region, multi-product outages within a single cloud are rare. Hopefully customers were forgiving in this case and see news headlines validating the extent of the outage.
