On January 12, 2024, Kagi experienced a service interruption that led to slow loading or complete page timeouts for users in various regions. The issue persisted for several hours as the team worked to identify and resolve the problem. It was discovered that the root cause of the issue was high contention on rows in the users table, which caused a steep increase in write latency. The team took steps to address the issue, including identifying and removing abusive accounts and implementing fixes to prevent the same issue from occurring again. Moving forward, Kagi plans to improve their communication processes and implement additional monitoring and limits to prevent abuse of their platform.
