As Langfuse's status page reports its own incidents (scheduled maintenance left out), read every few hours since May 26, 2026 (evidence )
41 reported incidents in the last 30 days, by 3 of the vendors Langfuse lists as subprocessors.
A subprocessor list names a company, not the service an incident touched. This does not show that Langfuse was involved.
