A system comprising: a client device; remote computing resources comprising a load balancing service and multiple server instances; a plurality of processors; and one or more computer-readable media storing computer-executable instructions that, when executed by the processors, cause the processors to perform acts comprising: receiving, at a load balancing service implemented by throne or more of the processors and from a client device, a first request to establish a connection to one of multiple server instances; based at least partly on the first request, establishing, by the load balancing service, a first connection between the client device and a first server instance of the multiple server instances; determining, by one of the client device and the first server instance, that less than a threshold amount of data has been transferred between the client device and the first server instance over a period of time; based at least partly on the determining, dropping, by the one of the client device and the first server instance, the first connection between the first server instance and the client device; receiving, at the load balancing service and from the client device, a second request to connect to one of the multiple server instances, the client device providing the second request based at least partly on the dropping;_and based at least partly on the second request, establishing, by the load balancing service, a second connection between the client device and a second server instance of the multiple server instances. a client device; remote computing resources comprising a load balancing service and multiple server instances; a plurality of processors; and one or more computer-readable media storing computer-executable instructions that, when executed by the processors, cause the processors to perform acts comprising: receiving, at a load balancing service implemented by throne or more of the processors and from a client device, a first request to establish a connection to one of multiple server instances; based at least partly on the first request, establishing, by the load balancing service, a first connection between the client device and a first server instance of the multiple server instances; determining, by one of the client device and the first server instance, that less than a threshold amount of data has been transferred between the client device and the first server instance over a period of time; based at least partly on the determining, dropping, by the one of the client device and the first server instance, the first connection between the first server instance and the client device; receiving, at the load balancing service and from the client device, a second request to connect to one of the multiple server instances, the client device providing the second request based at least partly on the dropping;_and based at least partly on the second request, establishing, by the load balancing service, a second connection between the client device and a second server instance of the multiple server instances. receiving, at a load balancing service implemented by throne or more of the processors and from a client device, a first request to establish a connection to one of multiple server instances; based at least partly on the first request, establishing, by the load balancing service, a first connection between the client device and a first server instance of the multiple server instances; determining, by one of the client device and the first server instance, that less than a threshold amount of data has been transferred between the client device and the first server instance over a period of time; based at least partly on the determining, dropping, by the one of the client device and the first server instance, the first connection between the first server instance and the client device; receiving, at the load balancing service and from the client device, a second request to connect to one of the multiple server instances, the client device providing the second request based at least partly on the dropping;_and based at least partly on the second request, establishing, by the load balancing service, a second connection between the client device and a second server instance of the multiple server instances.
