The new proxy architecture that was deployd for Adrian Flux and Bikesure has now been configured and for use with Sterling. Previously all requests were going to the content instance (sterling-wordpress) but are now being routed through a dedicated proxy of its own.
This will improve performance and stability as the traffic can be managed identically to the other brands, taking advantage of a shared firewall rule set.
Also, the requests are being handled at edge by the Worker process which means that edge feature such as content rewrite (for common content strings) and edge redirects will be available on the Sterling domains too. It will also improve the workflow and compatibility with content sub-sites on WP Engine.
