Answer: What is Open Projects Network mean?

Freenode, stylized as freenode and formerly known as Open Projects Network, is an IRC network which was previously used to discuss peer-directed projects. Their servers are accessible from the hostname chat.freenode.net, which load balances connections by using round-robin DNS.

On 19 May 2021, Freenode underwent what some staff described as a "hostile takeover" and at least 14 volunteer staff members resigned. Following the events, various organisations using Freenode – including Wikimedia, Free Software Foundation Europe, Ubuntu, CentOS, FreeBSD, Gentoo Linux, Arch Linux and LineageOS – moved their channels to Libera Chat, a network created by former Freenode staff. Others like Haiku or Alpine Linux moved to the Open and Free Technology Community (OFTC).. As of 16th August 2021, over a thousand other projects have also left Freenode.
