Here is the Original announcement
Sage Payment Gateway Scheduled Maintenance Monday, January 13, 2014
On Monday, January 13, 2014 Sage Payment Solutions will be performing system maintenance between the hours of 2 am and 5 am EST. During this period, Sage gateway merchants, including Virtual Terminal, Sage Mobile and McKesson Mobile merchants, may be unable to process transactions or settle batches. Every measure has been taken to keep the system updates as short as possible. This upgrade is part of our ongoing effort to provide you the most modern, robust and secure processing systems and solutions available. The Automatic Settlement Process will not run during this period, but will re-commence once systems are resumed.
