Realm status
Whether the realms and the login server are up right now, and how they have done over the last 30 days. A break of up to 15 minutes counts as a restart; anything longer is an outage.
Checking the realms…
Login server
Signs you in and shows the realm list. If it is down, nobody can log in, even when a realm is up.
Times are shown in your own time zone. The page updates itself every 30 seconds. Something wrong while the realm is up? See the known bugs or ask on Discord.
