CloudLinux OS 6 has officially reached its End-Of-Life on November 30, 2020. Software that reaches its end-of-life is no longer supported by developers, which means that you no longer receive critical security patches, updates, or feature changes. Unsupported software that receives no security patches could be vulnerable to future exploits, meaning your servers and devices could be targeted. With extended CloudLinux OS 6 support, you still get patches and updates as usual until 2024, giving you plenty of time to update to CloudLinux OS 7 or 8.
