I highly doubt this was "scheduled," they probably changed the outgoing server down message due to the large amount of overnight/early morning maintenance they've been doing. The server just crashed, and this was still set as that outgoing message.
It's a shame, because it's been what, 5-6 days, without a server crash? .. Things have been going so well
Right, and you also said that “The "Good" timing was actually labeled JE or JL, not N.“
N, in this equation should not exist. And based off the information you told us it does not.
Because either you are “Good” Timing, which is either JE, or JL. Or you are N, which in relation to the standard, that means you’re “Perfect.”
I’ve said it from the release that, “Good” doesn’t exist anymore with the existence of perfect. Either you are Good Early, or Good Late. Because the whole equation is based off of what is now a “Perfect” response.
In terms of a “Perfect” response, it would make sense that it’s JE or JL. What is “Good” in relation to “Perfect?”
It’s obviously not perfect, so you would have to technically be either “Just Early” of Perfect, or “Just Late” of Perfect...
