We have replaced the frontend web server on Web1 to Web56 with Nginx (previously it was running Apache). This means that all of our servers now run Nginx as their frontend web server. Note that Apache is still running behind Nginx to serve certain apps like PHP or Subversion. The change on Web1 to Web56 should be totally transparent but if you notice any issue open a ticket and we’ll look into it right away. The only change you should notice is that “static only” apps should now be a bit faster on Web1 to Web56 because they are now served directly by Nginx.
