What Does 24 by 7 Mean?

Does 24 by 7 really mean 24 hours every day and 7 days a week every week? It might depend on who you ask, but the one thing on which everyone agrees is that computers cannot run without occasional maintenance, upgrades, or even replacement. So what does 24×7 mean? In our case, it means we put into place many different controls to allow our systems to be running as many hours of the day, week by week, as they possibly can, while still allowing time for routine maintenance and necessary upgrades to hardware, communications and software systems.

CU*BASE: Unless your credit union has made special arrangements to be open to members on Sundays, Sunday is not considered a normal business day. Because there is no end-of-day processing or G/L interface run for that day, no posting to member accounts or the G/L can be done. However, unless we are using that Sunday for an upgrade or special activities (HA rollover, hardware upgrade, etc.), your staff may be able to access CU*BASE for routine work such as printing reports and performing inquiries on Sunday.

All offline from 1:00 to approx. 5:00 AM for for system IPL. For release date information, see Software Releases.

High Availability Rollovers

All services will be unavailable/offline during role-swaps.

See scheduled rollover dates below. Projected system downtimes will be provided as an alert prior to each rollover.

Scheduled Interruptions

Month-End Processing

Month-end processing will cause interruptions of service for It’s Me 247, CU*Talk, and ATM/Debit switches. The exact time and duration will vary depending on the day of the week on which month-end falls as well as other factors. Therefore, so that you can answer member inquiries, we will publish the actual interruption times on our web site on the first business day of the new month.

Release Implementation

The following chart explains the typical method for releasing upgrades to our key software products. Specific information on each release will be provided prior to the actual release date.


CU*BASE GOLD Edition ScreenshotCU*Answers typically releases three major upgrades to the CU*BASE software each year: one in the first half of the year, another in the 3rd quarter, and a year-end tax release. Release dates are published in advance and always fall on a Sunday.  In addition, we may perform occasional minor upgrades, as needed, between the major release months. All of these releases involve an update to the GOLD user interface on all credit union workstations.

Major releases are implemented early Sunday morning. During that time we must move all ATM/debit card switches to offline mode (transactions use offline limits). CU*BASE may also be unavailable for periods while updates are applied. (Remember that Sunday is not considered a normal business day for most credit unions and availability will be limited in any case.)

“It’s Me 247” Online/Mobile Banking

Like any other Internet application, It’s Me 247 requires occasional maintenance. Sometimes these events can be planned, but we also need to be able to respond quickly to day-to-day issues as they arise. Installations of new It’s Me 247 software are usually scheduled in advance, and will generally occur during the daytime on a normal business day. The logic is that if members have trouble logging in, they will feel much better if there is someone working at the credit union that they can call to help them complete a transaction.

itsme247_onlineWhen an unforeseen problem arises that needs to be corrected quickly, we are obligated to respond in as timely a fashion as possible. That might mean an interruption to It’s Me 247 at any time. We always do our very best to keep the interruption as brief as possible and take advantage of any cost-effective technology at our disposal to minimize the inconvenience to your members and staff. Information about these interruptions will be published on our Alerts web page, available to clients from the network links icon in CU*BASE GOLD.

NOTE: Depending on the nature of the maintenance, we can sometimes install a message stating “It’s Me 247 is temporarily unavailable,” but currently that message only works if the member accesses the system via If your credit union has a link from its web site which bypasses that initial page and goes directly to the login page, the member may not see that message at all. Learn more about It’s Me 247 upgrade releases.


cutalkAlthough they occur less frequently than changes to It’s Me 247, upgrades to the CU*Talk Audio Response application will also be scheduled in advance whenever possible, to take place during normal business hours. Other interruptions that occur because of unforeseen problems will be posted below for later reference.

Month-End Interruptions

Use this chart to assist when answering member inquiries about specific periods of time when service was interrupted during month-end processing. This chart will be updated as soon as possible after the first business day of the month.
