 * I am having an issue on several self hosted sites accessing update-core.php. 
   I am getting a 404 Error. I am also seeing slowness on the sites in general. 
   The site are spread out across several VM’s on 2 different hosts. All sites are
   running on Nginx 1.12+ and MariaDB 5.5+. Some sites are running PHP 5.6+ and 
   some are running PHP 7.1+. I have some success turning off all plugins but this
   is not consistently working.
 * This seems to have appeared suddenly.
 * Additionally, I have looked into issues with my VM hosts, website attack and 
   website compromise but I am not finding anything.
 * Note sure where to look next.

 * Nevermind. It was a self inflicted wound. I messed up our DNS server.
