Every time the server is offline the main page realm status is not updated.
This means that players will keep trying to connect altough the login server is off, rejecting login connections or other issue.
If u get a sucess login and u fail to connect to the realm it means a realm server problem.
Updating the login server and realm status on main page would prevent players from keep trying to connect. It might also help the server with less traffic
Website takes longer to display when a realm is down than updating current active players due to the extra time is takes verifying that it is indeed down.
