Frequent errors on GCP API Gateway

Question

I have an App Engine Standard Java 11 application served behind a GCP API Gateway. When I check the Cloud Logs I frequently see these errors like the following from API Gateway:

{
insertId: "5e1e0f456172eda03520c9fae065f312-1@a1"
jsonPayload: {
api: "//apigateway.googleapis.com/projects/abc/locations/global/apis/abc"
apiConfig: "//apigateway.googleapis.com/projects/abc/locations/global/apis/abc/configs/abc"
httpRequest: {
duration: "0ms"
hostname: "servicecontrol.googleapis.com"
httpVersion: "HTTP/1.1"
path: "/v1/services/abc.apigateway.abc.cloud.goog:report"
requestSize: "5003"
responseSize: "95"
status: 503
}
serviceConfig: "//servicemanagement.googleapis.com/services/abc.apigateway.abc.cloud.goog/configs/abc"
}
logName: "projects/abc/logs/apigateway.googleapis.com%2Fservice_control_queries"
receiveTimestamp: "2022-06-20T13:19:37.047238698Z"
resource: {
labels: {
gateway_id: "abc"
location: "us-central1"
resource_container: "projects/abc"
}
type: "apigateway.googleapis.com/Gateway"
}
severity: "ERROR"
timestamp: "2022-06-20T13:19:29.777308345Z"
}

What do these errors mean, should I be concerned?

Are you getting any error message? If so, can you share that? — Mousumi Roy, Jun 21 '22 at 10:39
Code 503 is usually interpreted as Service Unavailable. Check if it is possible that your function reached the maximum scaling... — Piotr W., Jun 21 '22 at 14:50

Asked the same question on ESPv2 github repo, the error means Google service control service is down, causing the request logs to be lost, but no other adverse effects to the application.
