Hello Ahmed (and all you Linux System Engineers/Web Developers!), I hope this finds you well! I'm a full-time blogger; my busiest blog is http://theadventurouswriter.com/quipstipsrelationships/ Unfortunately, I've been having serious downtime issues with all my 6 blogs for the past 6 days. All my blogs are WordPress installations, off of theadventurouswriter.com (my main website). My webhost provider is HostGator, and their techs have been trying to help me. But, they haven't been able to find the root of the problem. I just signed up for CloudFlare, but I think there's something else going on. I've been getting messages such as: The service “httpd” appears to be down. Server the.theadventurouswriter.com Primary IP Address 192.232.225.67 Service Name httpd Service Status failed ⛔ Notification The service “httpd” appears to be down. Service Check Method The system failed to connect to this service’s TCP/IP port.
