LJ staff is aware that things are fux0red.
If you're getting comment e-mail to an AOL e-mail address, as far as I know AOL has not put LJ's new IP address on their whitelist, so AOL is most likely eating comments as spam. (I have Gmail invitations for my friends, if y'all want any.)
status and lj_maintenance are likely to have the freshest updates on what's up with the heavily armed monkeys.
