I know no one uses irc these days and i belive irc is down as the ones below are down from a month now
https://www.mibbit.com/
https://www.kiwiirc.com/
http://irc.liberty-unleashed.co.uk/ as this used 6667
so those who have trouble connecting irc kindly move ur servers too
irc.libera.chat -> use 6697 for ports
Thankyou
