From the Library of Congress:
Over the weekend, as part of routine maintenance, the Library of Congress shut down a data center that hosts a number of U.S. Copyright Office systems, including the online copyright registration system, eCO. The Library of Congress attempted to reopen the data center on Sunday evening, but has been unable to restore access to Copyright Office systems. As result, eCO remains offline, and Copyright Office staff are unable to access internal shared network resources. Until service is restored, you will be unable to use the eCO system to file a copyright registration, and Office staff may be unable to access Office records.
Please note that during this outage, you can still file a copyright registration for your work(s) using a paper registration form. Fillable PDF registration forms are available atÂ http://copyright.gov/forms/. For further information, please contact 202-707-3000 or 1-877-476-0778 (toll free).
The Library of Congress informs us that it is working to resolve the problems as expeditiously as possible, but we do not have an estimated time for service resumption. A notification will be sent when service is restored.
We apologize for the inconvenience.
