Techniques for enabling system redundancy for group-based communication platforms are discussed herein. In some examples, a user may post a message to a virtual space of a communication platform. The communication platform may transmit the message to virtual space servers which manage the virtual space within which the message originated. In such examples, a virtual space may be associated with a plurality of geographically distributed virtual space servers. Based on the virtual space servers receiving the message, the virtual space servers may send the message to one or more gateway servers that are subscribed to the virtual space servers. Gateway servers may be connected to client devices associated with user profiles. Upon receiving the message from the virtual space servers, the gateways servers may send the message to the recipient client devices. The recipient client devices may display the message via a user interface of the communication platform.
