historically, expansions have gone live at midnight PST.
if i remember correctly, mop and cata were both "activated" at midnight, and there was zero downtime
By "activated" he means that there was no downtime but every portal and opening quest essentially crashed/could not be completed. Any med-high pop server had queue times and it was IMPOSSIBLE to start leveling for at least an hour or two until players started to thin out across new areas.
Here's to hoping that doesn't happen this time!
