Bancolombia Announces Scheduled Blackout for System Maintenance
Bancolombia has announced that its digital platforms will undergo a temporary service suspension on the night of February 25. This action comes in response to significant outages and technical failures that affected millions of users from February 22 to 23. The bank communicated the situation through its social media channels and a letter to its clients, emphasizing its commitment to the stability of its systems.
Purpose of the Scheduled Blackout
In its official announcement, Bancolombia explained that the blackout is part of a planned maintenance protocol necessary to stabilize its digital services. The bank clarified that this is not a result of a cyberattack, assuring clients that their funds and sensitive information remain secure.

During the scheduled blackout, certain services will continue to operate, while others will be temporarily unavailable:
Available Services:
- Transfers: Users can transfer money to both registered and unregistered Bancolombia accounts using the Mi Bancolombia app.
- ATM Withdrawals: Users can still withdraw cash from ATMs.

Bank’s Apology and Acknowledgment
In its correspondence to clients, Bancolombia acknowledged the impact of the recent issues and issued a heartfelt apology. They emphasized that they had failed to keep a crucial promise: ensuring that clients’ money would be accessible when required. The bank reiterated that keeping customer trust is of utmost importance, and service reliability is non-negotiable.
Background of the Issues
The outages were traced back to a scheduled technology update that was supposed to enhance system efficiency—capable of handling over 80 million transactions daily. However, a technical mistake led to complications, and the attempt to reverse the update resulted in extended service interruptions. Bancolombia assured that this issue has been communicated to the Financial Superintendency of Colombia for oversight.
Future Communications and User Guidance
The bank has committed to maintaining open lines of communication with clients, promising updates on the progress of the scheduled maintenance. To alleviate user frustration during this period, Bancolombia has recommended that clients withdraw cash and plan their physical purchases using debit or credit cards cautiously.
Conclusion
As Bancolombia navigates this challenging situation, the bank aims to ensure its technological infrastructure is robust enough to prevent future outages. Clients are encouraged to stay informed through Bancolombia’s official channels as they work toward enhancing service reliability and customer experience in the long run.
