Deployment times for config changes have been operating at the sub-5m timeframe for at least two years. It used to take hours (never days) to propagate changes across the server estate, but not anymore. And while we were admittedly late to the DevOps train, we have made up lost ground. We have nearly 100 individual APIs to control almost any aspect of our products. CLIs if you don't want to write to the API. A Sandbox to test config changes locally. The ability to validate OAuth tokens at the Edge, cache GraphQL responses, and throttle and/or quota API traffic on a global basis. Hashtag "legacy CDN."
