If you're experiencing difficulties connecting to IRC, it's not your fault; the
#freenode channel's subject is currently:
"""
We're currently experiencing what appears to be a DOS attack against our
servers. Some servers are offline, and local IPs appear in the rotation,
meaning that some connections will fail. | 127.0.0.1, 127.0.0.2 addresses in
DNS are for mitigation and will be removed when this passes
"""
I've been able to connect via
https://webchat.freenode.net/ but not through my
IRC client.
Hope this helps,
Shai.
