We've, this last weekend, added 2 new IRCd's to the IRC network; IRC1 and IRC4 are both online due to user donations from Phatal for the shell's for them.
The provider for these shells is reverse.net who is located in the Equinix Chicago datacenter.
Not all of the links have been finalized as the link lines have to be added on all servers; however they are all currently online and connected to eachother.
We expect everything to be finalized by this coming weekend.
Additionally, IRC5 will be down sometime this month for server maintenance.
