Update on the Service Disruption
On the 25th, we experienced a disruption that affected access to the receipt archive in our platform. We want to share with you what happened, the steps we are taking to prevent it from recurring, and also thank you for the valuable feedback we have received.
What happened?
Our platform processes millions of receipts every month. At the start of each month, a new receipt archive is created and gradually filled with incoming receipts. As the month progresses, the system load naturally increases.
In August, we observed a significant surge in usage, with activity more than doubling at the beginning of the month and remaining high throughout. On the 25th, this high load coincided with a database restart. During the restart, the cached results that normally ensure fast and smooth performance were temporarily cleared. Because some indexes had not been optimally maintained, the database had to handle the full workload directly. This resulted in very long response times, and in some cases, requests could not be completed.
How were you affected?
During the disruption, some users were unable to access their receipt archives. Requests took too long to process, and the system was unable to rebuild cached results quickly enough. This may have prevented receipts from loading, or caused the process to time out.
What are we doing to prevent this from happening again?
We have thoroughly analyzed the incident and are implementing the following improvements:
-
Enhanced index maintenance to ensure efficient database searches even under heavy load.
-
Expanded caching mechanisms to reduce dependency on direct database queries during usage peaks.
-
Strengthened monitoring and alerting to detect and respond quickly to unusual load patterns.
-
Capacity optimization to better handle temporary spikes in usage.
Thank you for your feedback
We are grateful for the positive feedback we received regarding our communication during this disruption. It means a lot to us to know that our transparency and timely updates are appreciated.
We have also received valuable input on improvements in Expense. One customer highlighted that receipt matching is now significantly faster and more reliable. Feedback like this reassures us that the changes we make deliver real benefits in your day-to-day work.
