On 10 July 2007, most of ZiRC split up due to issues in leadership, with most of the admins and servers creating the synIRC IRC network.

Only a single server remains to host the ZiRC network. On 15 July, all channels advertising the new network were banned.

After 2.5 years synIRC has become the 19th biggest IRC Network listed on SearchIRC.com and 20th biggest IRC Network listed on Netsplit.de with an average of over 4800 users and 1200 channels.

After 5 years synIRC has become the 11th biggest IRC Network listed on SearchIRC.com and 17th biggest IRC Network listed on Netsplit.de with an average of over 6200 users and 2000 channels.
