Bad Debian repository cache on Docker Hub?

As can be seen at the bottom of this build log, and among other projects over the past couple of days, Docker Hub is failing on retrieving a package that matches it’s checksum. As the build works locally, and on other docker image build services, this would indicate that (if Docker Hub is using a cache for package repositories) that server revalidation is not being performed, and the cached package is either corrupt or not being retrieved properly.

Here is a snippet:

Get:124 wheezy/main sqlite3 amd64 3.7.13-1+deb7u2 [119 kB]

Same problem here. Locally it works and not on docker cloud.
