It looks like today there was maintenance scheduled to deprecate support for certain categories of SSH keys: https://github.blog/changelog/2026-09-22-security-improvemen...

> November 4, 2026: We’ll have a brownout of the removal of the ssh-rsa signature type (i.e., RSA keys using SHA-1) and the diffie-hellman-group-exchange-sha256 key exchange algorithm.

I guess something went sideways.

nothing :) hope they'll release a statement soon, this is was an assumption on my side, it might be totally wrong. I had intermittent issues with basic git pull/push ops locally so I went to dig a bit. ps: if you do have money to spare, consider donating to the EFF (https://www.eff.org) though B)

EC keys should be much smaller... this is only valid for id_rsa SSH keys
