A routine upgrade broke ssh logins on some Gentoo boxes due to the
deprecation of LPK patchsets for openssh. We have since fixed the glitch as
it were, and ssh should be working again.

We believe:

dev.gentoo.org
git.gentoo.org

Were the worst affected.

We apologize for the inconvenience. If you have any questions or continue
to encounter issues SSHing into these boxes please let infra know.
