Incident Date: October 22, 2023
Incident Duration: Approximately 1 hour
Affected Services: All services
Incident Description:
At approximately 9:30 AM CET on October 22, 2023, an incident occurred on our database due to a disk space issue. The disk associated with the DB instance reached full capacity, causing a disruption in our database operations. As a result, all services dependent on this database were impacted.
Impact:
The incident rendered it impossible to perform write operations on the database, leading to a halt in functionality for all of our services. This disruption lasted for around one hour until our developers were able to mitigate the issue.
Resolution:
The incident was resolved by leveraging auto-scaling capabilities and expanding the disk size, alleviating the disk full issue and restoring normal operations.
Preventive Measures and Recommendations:

1. Alert Monitoring: Monitoring to prevent disk size reaching full capacity.
2. Auto-scaling Configuration: Enable auto-scaling function which helps in automatically adjusting resource capacity to accommodate increased demand.

By implementing these measures, we can proactively address and mitigate similar incidents in the future, ensuring the continued reliability of our services.
