No, you're mistaken, maybe something here is confusing and I'm interested in knowing what. Is this "persist mode" that confused you ? Here the doc is referring to the "persist" keyword (now obsoleted by "option persist"), which forces sticky connections to go to their server even if the server looks down or is disabled. Otherwise the difference between maintenance and weight zero precisely is for sticky connections which don't go to the server in maintenance mode. There's a simple way to understand all this : when you have to operate on your server, first you lower its weight to zero to take it out of load balancing, you wait for some time, and only then you put it into maintenance mode in order to be able to operate without anybody other than you being able to reach it. BTW, health checks are also disabled in maintenance mode so that they don't perturbate operations. Regards, Willy
