It's neither one of their jobs. It's up to another team to decide if a public written response is ok or not.
The best response is the server related issues being fixed. Not all responses have to be written 😉.
"The best response is the server related issues being fixed"
I will bet any amount that the issue isn't fixed. Peak hours are over, they waited the problem out. Wait until the next weekend with an event and we'll see the same thing happen again.
My educated guess is that there was no issue (from their PoV).
They just enforced more astringent parameters on the login servers for the weekend to ensure that the servers remained operational despite the sudden spike in demand caused by the Epic promotion + ESO+ 'trial' + Event.
The issues some of us experienced - being disconnected at that crucial handshake after the queue 'popped' - are (again from their PoV) unfortunate, but probably within tolerance given the exceptional circumstances.
It doesn't make it any less frustrating from an end user point of view, but from their perspective is probably all within acceptable parameters.
If there is any official word on the matter it will just be a non-apology written in corporate doublespeak.
That's the easiest, fastest, most accepted way of communication.
How about "Our apologies. The EPIC giveaway, ESO+ tryout and Zenithar event at the same time turned out to be a way larger success than we ever anticipated. Unfortunately, an immediatly fix without breaking any of the three events was not possible. We will make sure, enough processing power is available in the future and we also will make sure events don't overlap. As a remedy, 3 crown crates have been gifted to your account and the Zenithar event has been prolonged by two days."
