Even by the definition you provided, a "quick" restart of the realms could take a few hours because it's an MMORPG, not pacman.
Name a current year MMO that takes "hours" for a server restart. WoW server restart takes like 10-15 minutes. Warframe (if you wanna count it) takes a couple minute and you can even stay online if you are in a mission. GW2 doesnt even restart their servers for updates.
