Typically, customer sites have load balancers in place and configured prior to the start of the Spok Mobile installation. Load balancers must be configured properly to ensure that the system can successfully fail over and be monitored. The supported health monitor for the 2000x MXPP ports is tcp_half_open. The supported health monitor for ports 443 and 8091 is HTTPS.
HTTP compression should not be enabled with the load balancers.
