This can depend on a few factors. The main reason is that the server’s socket listener stops responding and valtron has to restart the server. Other reasons can be attempted DDOSes on the server or it could be overloading and not be able to handle the constant network traffic. As Escargot right now is hosted on one server instance, the first and third reasons can be more common. In the future, we hope to federate Escargot to separate servers, which should alleviate some of the server problems.
