I love reading the source code of WoW private servers. They are not the official code but for example TrintyCore is quite nice c++ code.

The WoW development diary talks abit about their server code and how they handle the load.

Its a book https://whenitsready.com/wowdiary/ originally sold as a kickstarter by one of the original Blizzard mappers made from notes they wrote while working on original wow. They did some AMAs[1][2] with other wow developers that sort of touch on some of the topics discussed here.
