It's currently a little after 8 am in Irvine, and assuming the maintenance started at the intended 5 am, we only have a little under an hour left of the estimated maintenance duration. Here's hoping that's actually the case, and we see servers coming up within the hour. If that's not how today plays out, we'll be sure to let you know.
Update: We've hit the 4 hour mark and run over, it's been just shy of 40 minutes past the estimate. We'll see how much longer this goes on. Personally, I'd be fine if the servers were down all day long if it meant the rampant lag across many servers was resolved because of it... but that's just me! Either way, we'll be keeping an eye on it.
Update #2: Servers are starting to come back on, ladies and gents.
