Routing log-based information between production servers and logging servers is disclosed. A log entry for a logging server is generated at a production server. A shard identifier is computed for a shard associated with the logging server based on application of a hashing algorithm to properties associated with the production server. The hashing algorithm and properties are selected to prevent or minimize the likelihood of computing of the same shard identifier by another production server for the same shard associated with the logging server. The log entry is transmitted to the shard associated with the logging server. A determination is made that the logging server has malfunctioned by detecting that the log entry transmitted to the shard is absent. In response, another shard identifier is computed for another shard of another logging server and a subsequent log entry from the production server is transmitted to the another shard of the another logging over. No load balancers are used by the routing system.
