Disclosure: I work on Google Cloud (but I'm not in SRE, oncall, etc.).<p>As the updates to [1] say, we're working to resolve a networking issue. The Region isn't (and wasn't) "down", but obviously network latency spiking up for external connectivity is bad.<p>We are currently experiencing an issue with a subset of the fiber paths that supply the region. We're working on getting that restored. In the meantime, we've removed almost all Google.com traffic out of the Region to prefer GCP customers. That's why the latency increase is subsiding, as we're freeing up the fiber paths by shedding our traffic.<p>Edit: (since it came up) that also means that if you’re using GCLB and have other healthy Regions, it will rebalance to avoid this congestion/slowdown automatically. That seemed the better trade off given the reduced network capacity during this outage.<p>[1] <a href="https://status.cloud.google.com/incident/cloud-networking/19016" rel="nofollow">https://status.cloud.google.com/incident/cloud-networking/19...</a>
