Scary ‘Possible DNS spoofing’ ssh error

I just tried pushing a bazaar branch, and got a scary message that said “WARNING: POSSIBLE DNS SPOOFING DETECTED!”. Turns out my web host (dreamhost) moved my site to a new server. The error was because the RSA key had changed. I had to poke around to confirm that it was legit, and not a spoof.

But hot damn, that made my heart beat. I’m glad my everyday tools “just work”, with things that can confirm the box is the same.
