npm ssh error doesn't replicate from shell

When trying npm install, I get error:

1206 error node v0.12.0
1207 error npm  v2.7.4
1208 error code 128
1209 error Command failed: git clone --template=/root/.npm/_git-remotes/_templates --mirror ssh://git@git.spindle.factfiber.com/schematist-postgres.git /root/.npm/_git-remotes/ssh-git-git-spindle-factfiber-com-schematist-postgres-git-8e4b2071
1209 error ssh: Could not resolve hostname git.spindle.factfiber.com: Name or service not known

However, when I try the very command reported from the shell:

git clone --template=/root/.npm/_git-remotes/_templates --mirror ssh://git@git.spindle.factfiber.com/schematist-postgres.git /root/.npm/_git-remotes/ssh-git-git-spindle-factfiber-com-schematist-postgres-git-8e4b2071

It works:

Cloning into bare repository '/root/.npm/_git-remotes/ssh-git-git-spindle-factfiber-com-schematist-postgres-git-8e4b2071'...

I tried this a couple times in case it was a temp dns glitch. Does anyone know what could be happening?
