lifecycle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A visitor requests a page.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The browser sends a request.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS resolves the domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The request reaches the web server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The web server calls PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PHP queries MySQL.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress assembles the page.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The page

incoming requests exceed available resources, the server deliberately starts rejecting traffic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The goal is survival.<\/p>\n\n\n\n<p
