== Read-only Mode == Repositories can intermittently be in "read-only" mode. This means that nothing can be written to the repository. This can be for a number of reasons: * We're upgrading our storage segments, and can't accept new data. * We're rolling out changes that require no new writes. * Safety reasons (compromised accounts, etc.) Read-only mode usually only lasts for a few minutes, so if your repository has been marked read-only, try it again a little while.
