Ni cerita semalam. Pagi2 dah greeted with report of 502 bad gateway by razakschool webmaster. Belum jumpa Solution, still in the middle of research what cause that error but temporary solution is to restart httpd service. Early hypothesis is we got some attack to the server but no prove yet. Another hypothesis is the server is not yet configured for high traffic. Well, everything is just an assumption. Seeking help from utm webmaster group but looks like no one have the related knowledge of nginx
