Google tag gateway for advertisers via Google Cloud Platform — general availability

'This integration allows you to leverage Google Cloud Platform's Global external Application Load Balancer to send data through your first-party web infrastructure before it is relayed to Google.'

What it breaks

Nothing breaks; a first-party path changes what ad blockers and ITP see, so collection counts can rise after enabling it — annotate the date.

Who it hits: Sites on GCP, Cloudflare, Akamai, Fastly or CloudFront considering the gateway.

The fix

If you enable it, annotate the date and expect a step up in collected events.
