Update regarding the service disruption in Varbi today (2026-08-28): Earlier today, an improvement to Varbi’s messaging functionality was deployed. The update had successfully passed all standard quality assurance and testing procedures. However, an unforeseen inefficiency in the code caused a significant issue within the database environment, which resulted in the service disruption. Once the root cause had been identified, our Technical Team developed and deployed a corrective fix. During the investigation and resolution process, the message inbox and outbox functionality was temporarily disabled to help ensure system stability and limit further impact. The fix has now been successfully implemented, and we have not seen any recurrence of the issue. We would also like to emphasise that this incident was caused by an internal system change and was not related to any external source or security attack. No data was lost, compromised, or transferred outside of our servers. We sincerely apologise for any inconvenience this may have caused and appreciate your patience and understanding.
