On-demand startup of offline servers and connection routing

A computing system comprising:

• one or more processors;
• one or more non-transitory computer-readable storage media storing instructions which, when executed using the one or more processors, cause the one or more processors to perform:
• receiving, at a proxy server computer from a client computing device, a request to access data over a network;
• identifying, at the proxy server computer, a particular server computer that is separate from the proxy server computer to fulfill the request from the client computing device;
• determining, at the proxy server computer, that the particular server computer is unavailable to the client computing device;
• in response to determining that the particular server computer is unavailable to the client computing device, performing, at the proxy server computer:
• maintaining a transport layer connection from the client computing device;
• while maintaining the transport layer connection, initiating startup of the particular server computer;
• determining that the particular server computer is available to the client computing device;
• in response to determining that the particular server computer is available to the client computing device, proxying the connection from the client computing device to the particular server computer.
