News and Information

Pegasys application will be undergoing system maintenance and will be unavailable from Thursday, February 16, 2017 (7:00 pm ET) - Tuesday, February 21, 2017 (7:00 am ET)

The Purpose of this Maintenance release is to deploy the following:

Pegasys will be unavailable due to the implementation of the Pegasys Cloud Hosting Migration. To limit the outage to only one business day, the implementation will occur over the federal holiday weekend. The Pegasys Cloud Hosting Migration will transition USDA's Financial Management System to the CGI Federal Cloud, resulting in a new infrastructure for development, production and testing environments as well as increased taxpayer savings, scalability, security and performance.

AAS applications will be available during this downtime, however, the following integrations with Pegasys will be suspended for the duration of the release window and include:

  • Billing Files
  • Accrual Files
  • Agreements
  • Invoices
  • All other data transmissions & files

All held transmissions and files will be forwarded to Pegasys upon notification of system availability.

Specifically, users are advised that ASSIST funding must have approved agreement transactions established in Pegasys prior to 7PM Pegasys cutoff in order to utilize funding on a modification during the outage period.

All ASSIST invoices received and processed during the outage will be queued and transmitted upon notification of system availability.

ASSIST Billing transactions need to be created and transmitted prior to the outage to insure the transactions are processed into the Pegasys billing cycle for mid February.


As always, if you need assistance while using the GSA ASSIST portal, please call our Support desk at 877-472-4877 or email: aasbs.helpdesk@gsa.gov.
