Hi all, When I started my day today, I realized how strange our caching was acting up. While the site was still running without problems for most of it, the memory usage was a bit higher than usual. After some digging, I realized that most of the requests weren't cached and the logs were flooded with POST /wp-cron.php (see attachment). You can see the Fastly caching graph at the rectangle, this is when I made the change. After the change, you will see that the cache RATE jumped to 100% and the passes and requests dropped. After some reading, I realized that its either that somebody is creating a problem by constantly hitting our /wp-cron.php file(an attacker?), or the caching layer checks too enthusiastically. A sure thing is that I do not remember seeing that much requests, it would had jumped at me earlier. In any case, the wp-cron.php will not be called from the outside anymore but managed by our very own crontab. Problem solved. -- Regards, Renoir Boulanger | Developer operations engineer W3C | Web Platform Project http://w3.org/people/#renoirb ✪ https://renoirboulanger.com/ ✪ @renoirb ~
