We now perform SSH Host Key connection checks before connecting to any remote host.
By default, this security feature is enabled on newly connected servers, preventing us from logging into your server if the host key does not match. For example, when you: - Preprovision a server
- Change DNS and point to a different machine by mistake
- Lose a floating IP
- BGP poison attacks
While the risk was minimal, we saw it fit to add this extra level of security. You can also see the Acsci art form of your host keys to confirm the connection is correct visually.
This feature can be turned off if you do not wish for the extra check level in cases where you expect the host key to change. You may be better suited for agent-based backups. (Existing customers will need to manually enable this feature)
