LibreSpeed Failure

Update timeline

1. monitoring Mar 16, 2026, 08:58 AM UTC

   The certificate issued by public LibreSpeed servers has expired. As a result, any UXI sensor executing a LibreSpeed test against the public servers will raise an alert due to the expired certificate. Turning off the "secure" toggle on the LibreSpeed test configuration forces the sensor to skip any TLS validation of LibreSpeed test. This is a temporary solution to work around the expired certificate error but may not be appropriate for some environments. Alternatively the alert can be muted on the dashboard itself, however the test will not be run due to the failed certificate validation. If your environment depends on the output of LibreSpeed throughput tests and an insecure configuration for the test is not possible, it's recommended that you configure a local LibreSpeed server to continue executing the tests.

2. resolved Mar 16, 2026, 02:25 PM UTC

   The certificate issued by public facing LibreSpeed servers has been updated and the sensors should resolve any open errors which were created against the service shortly. Please revert any changes applied to your dashboard configuration to account for this error as the core issue itself has been resolved.
