Lichess as an application is very impressive, and I use it frequently. The one thing that is somewhat more annoying is the way in which there is a (daily?) restart of the servers, causing strange behaviour in-game. For example, around the restart time, sometimes the restart warning falls away and it seems like you are waiting for the other player to make a move, when in fact you are disconnected.

Is there a reason why restarts happen this way and there isn't traffic draining between servers as they restart one at a time?

There is only one server. Or well, there are lots of servers that make up Lichess but they mostly do different stuff. There is only one main server which handles all the core stuff including games.

Also, restarts usually aren't daily. They generally are around once a week. Though sometimes when a new feature is seeing rapid iterations or an important enough bug is found, restarts can happen a few days in a row.
