Disclosed are examples of systems, apparatus, methods, and computer program products for message delivery in a distributed server environment. In some implementations, a first dispatcher component can control an event stream. A first connection can be established between a first server and a client device. The first dispatcher component can identify a first event associated with the client device. A first message including an identifier can be generated. The first message can be provided to the client device. It can be determined that the first connection is unreliable. A second connection can be established with a second server responsive to receiving the identifier from the client device. A temporary second dispatcher component can be instantiated. The temporary second dispatcher component can identify a second event. A second message can be generated based on the second event. The second message can be provided to the client device.
