The Cloudflare 520 Mystery: How a Threat Intel Feed Took Down One Customer Through One Specific PoP

CloudFlare Logo

The Setup

A client running an OpenCart store and a WordPress site reported intermittent Cloudflare 520 errors. Initial reports mentioned issues with custom security software they were running (a proof-of-work challenge being injected via auto_prepend_file), which we helped them disable. The 520s continued.

The Pattern That Made No Sense

Over the following days, the client did remarkably thorough testing on their end and identified a pattern none of us could explain:

  • 520 errors only occurred when traffic routed through Cloudflare’s LAX (Los Angeles) PoP
  • Other Cloudflare PoPs worked perfectly
  • DNS-only mode (no proxy) worked perfectly
  • Direct origin access via hosts file worked perfectly
  • A clone of the site on a different host, behind the same Cloudflare configuration, worked perfectly

By every measure available to them, the issue was specific to the combination of their site + Cloudflare LAX + our infrastructure.

MDDHosting ObjectCache – Memcached and Redis Manager Updated

MDDHosting ObjectCache Memcached and Redis Manager

We are thrilled to announce the latest updates to our Object Cache cPanel Plugin that will help you manage Memcached and Redis more efficiently. We made management of these services even more straightforward and user-friendly.

Here’s a quick rundown of the new features:

Status Indicator: The status of the plugin is now indicated with a colored circle – green for running, yellow for starting or stopping, and red for stopped. This change will help you quickly identify the status of the plugin at a glance, without the need to check logs or other indicators.

Refresh Status Button: We have updated the “Refresh Status” link to a blue button. This change makes it more apparent that this button refreshes the status of the plugin and enables you to check for updates quickly.

Enable/Disable Button: The Enable/Disable links have been converted to buttons that are green for Enable and red for Disable. This change makes it more intuitive to turn on or off the plugin, and it also makes it easier to identify the current status. We debated between green to start, or green to show it’s already running on the buttons – let us know your thoughts!

Improved Text Display: We have made the text boxes for the socket display in a monospace font and bold. This change makes it easier to read.

Live Start/Stop Timer: We added a live timer until the next start/stop process for Memcached and Redis. The timer provides real-time information on when the services will start or stop next. This is especially useful when you need to make sure that the services are up and running before you begin working.

These updates are now live and available for use. We believe that these improvements will help our users manage Memcached and Redis more efficiently, saving them time and effort. If you have any feedback or suggestions, we’d love to hear from you!

cPanel AutoSSL – Automatic Free SSL for All Domains

AutoSSL PadlockAutoSSL is going to change how webmasters secure data transferred to and from their sites.  For the longest time SSL was an additional expense that many webmasters chose to forego as it wasn’t required for the operation of their websites.  The time when not having SSL is the norm for most sites is coming to an end.  Generally SSL has been reserved for usage by those that send or receive private information such as your name, address, email address, and phone number or even your credit card information.

Google and other search engines are already giving preferable ranking to sites with SSL.  For quite some time we’ve offered Let’s Encrypt to our customers so that everybody has access to freely accessible SSL for any site they wish.  cPanel has taken this a step further and created what they refer to as AutoSSL.  AutoSSL generates and installs a domain validated SSL certificate on all active domains on a server that are not already protected with SSL.
