Lately I've been noticing huge traffic drop across my network. After checking Google Webmaster Tools it seems Google is no longer able to crawl some of my internal pages due to me unknown reason. I tried Webmaster Tool, Fetch as Google and sometimes entire page content is missing. This is example: HTTP/1.1 200 OK Date: Fri, 06 Jul 2012 11:43:52 GMT Server: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.3.6 X-Powered-By: PHP/5.3.6 Content-Length: 1 Connection: close Content-Type: text/html PHP: Or some other website: The page seems to redirect to itself. This may result in an infinite redirect loop. Please check the Help Centre article about redirects. HTTP/1.1 301 Moved Permanently Date: Fri, 06 Jul 2012 11:47:03 GMT Server: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.3.6 X-Powered-By: PHP/5.3.6 X-Pingback: http://fixexe.com/xmlrpc.php Location: http://fixexe.com/keeping-your-chat-logs-safe-with-encryption/ Content-Length: 0 Connection: close Content-Type: text/html; charset=UTF-8 PHP: I believe this could do something with miss PHP configuration, .htaccess, Apache, or either some mod running. I have a dedicated CentOS server running cPanel, Varnish Cache and CSF firewall. After work is complete I will pay via PayPal.
