On July 24, 2025, the Pathfinder instance us.leanix.net was unavailable for approximately 6 minutes, from 12:30:50 UTC to 12:36:40 UTC. All customer requests targeting this instance failed. At least seven customers have been affected.
The issue was mitigated by redeploying the affected instance.
During a routine update, one of our gateway servers reloaded its configuration. Due to connectivity issues, the server was unable to reach any DNS servers, resulting in its failure to resolve the IP address of the upstream server. Consequently, the web server was not able to respond to requests to the respective upstream service.
We will utilize Azure’s internal DNS servers to reduce latency and dependency on internet connectivity. Furthermore, we will consider hot reloads in scenarios like this to improve recovery times.
