We have an unmanaged server running Apache. An hour ago the site went down and it would not restart. Turned out that mod_pagespeed.so listed in httpd.conf could not be found. I commented it out and Apache started up fine.
But where’s mod_pageseed.so gone and why? It’s been in its normal place /dh/apache2/template/lib/modules/ since we got this server 2 years ago. We’ve never touched those files and I’m the only one with su access. Nothing else has gone missing. I’ve done a complete search and mod_pageseed.so is nowhere on the server.
I’m putting this out in case anyone else has similar experience. Could it be a DH update to managed servers accidentally hitting unmanaged servers too?
