Many apps such as https://www.spotify.com/uk/ are returning a 404. Our load balancers are valid just not able to match any url rules no traffic in logs either. Cloud CDN is still serving traffic.
Our alerting triggered at 17:36 GMT
Edit: 18:07 No official update to status page but firebase real time database issues added to known issues in support. Services such as Datadog, Snapchat all having issues. Traffic is unable to route to backend services. Does not seem to impact services such as Cloud Run
Edit: 18:10 Just as added to official status page our 404's seem to be resolving. https://status.cloud.google.com/incidents/6PM5mNd43NbMqjCZ5REh
