System Maintenance Window

Sunday between 4:00 a.m. - 10:00 a.m. central time

ASK has regular system maintenance scheduled every Sunday from 4:00 a.m. – 10:00 a.m. There may be instances during a maintenance window where trading partners are still able to connect, upload, and download files. There may be other instances where trading partners will not be able to connect, and therefore will not be able to upload or download.

If a trading partner is experiencing a connection disruption, is not able to upload, or is not able to download, please wait until the system maintenance timeframe has ended and try again. If the connection disruption persists then please send an email to [email protected] and a support specialist will review your connection on Monday morning.
