The difference in experiences just in this thread shows that it isn’t the Zeni servers.
The problem for some people originates elsewhere, and those people are flinging poo at Zeni in blind rage. Zeni appropriately ignores them.

I've been doing questing/overland/delves, PC/NA. Haven't seen any performance problems. Meanwhile, people doing pvp in Cyro have all sorts of problems regardless of an event or not.
(of course, particular events can have an effect - Mayhem will make it worse because more people will go into pvp, aggravating the Cyro issues. ESO+.... eh, people using the free trial are decorating their houses, farming mats into their craft bags, and doing quest & dungeon DLC they don't own. Not a 'crush the servers' situation.)
