On the lower right portion of the operator console, there is a server connection strength network icon. The connection strength network icon is a measure of the communication response time from the computer to the server and back to the computer.
For instance, an HTTP request is sent to the server to check for available chat response or a new chat request. 1) The operator console makes a request to the server, 2) the server responds to the request and generates an output and 3) the output is sent back to the operator console - total of 3 communication steps to display an updated information to the operator. The total communication time of the 3 steps will be the "Server Connection Strength" network icon. If there is an internet lag between any 3 steps, it will affect the connection strength network icon bar. As long as the indication bar is displaying a signal and not a disconnected icon, the operator console should be fine. If the server connection strength bars are red, you may notice a slightly delayed in responses during a chat session.
Keep in mind, there are external factors (internet provider, computer internet activity) that can effect the communication to the server. The server may be fully functional but if your internet provider is having a temporary connection delays, it will ultimately effect the overall connection to the server, thus effecting the chat system. If nothing on the server has been changed yet at times the network status goes to red or at times disconnect, it is most likely the external factors. These situations are temporary and internet connection generally regains normal in time.
