October 2020 Release Dark Days for the Common Working File (CWF) Hosts

For the upcoming October 2020 Release, the Common Working File (CWF) will be observing Dark Days starting Friday, October 2, 2020, through Sunday, October 4, 2020. The Dark Days are needed to ensure the completion of weekly, monthly and quarterly processing and the installation of the October 2020 Release.

The Dark Days will not affect your ability to access beneficiary eligibility, claim status, or other information through Palmetto GBA’s eServices portal.

During the Dark Days, our Interactive Voice Response (IVR) system will not have access to the CWF, so users will not be able to check beneficiary eligibility or claim status through our IVR. The IVR will be available for users to check the payment floor or the last three checks paid, and to request a duplicate remittance notice using a check number.
