2 hours?

The wiki is updated by the players, not the devs, and does not have a 100% accuracy guarantee. Wiki editors rarely know anything that the rest of the playbase does not know; our job is mainly compiling the information available into an easily digested format. If you're worried about the wiki being inaccurate, find the actual information and improve it yourself.

Well, that's my point. It's a compilation of information available. In this case, saying that maintenance has been extended by X hours is not information, it's speculation. Nexon may be a couple of minutes late, they may be half an hour late, they may be hours late. But it's completely inaccurate to simply announce something that has not been announce (i.e. that maintenance has been indefinitely extended, which would cause players to think something seriously went wrong) or even worse, to pull a figure out of thin air (as was the 3 hour figure - Nexon never announced that it was being extended by 3 hours, they were just 15 minutes past the two hour extension mark.)

I'm not worried about the wiki being inaccurate, I'm more worried about speculation and false information being added to it.

15 mins = undetermined until announcement. They announced it late and I have yet to caught it. "Usually" they announce it 10~20 minutes prior to ending.

Either way, it's not information that has any source, it's speculation. I don't think speculation should be on the wiki.

Perhaps it would be better to say something like: "Maintenance is delayed/has not ended, Nexon has made no announcement yet."
