Failure: [Errno 8] nodename nor servname provided, or not known

[Adjo]

I'm using: 
gsutil -h "Cache-Control: public, max-age= 1000000" cp -r -t -z jpg -a public-read uploaded_images gs://static.tinkworld.com/

After a few hundred files successfully upload, I get this error:

Failure: [Errno 8] nodename nor servname provided, or not known.

Any ideas? Thanks!
