Due to popular demand, here are the exact posts that went up yesterday regarding the PTR and their up and down status. Or is it down and then up?
At about 1:30PM Eastern I see this. We will be taking the 2.4.2 PTR down shortly and ending the 2.4.2 PTR phase. Thank you to everyone [...]

First up we have a little bonehead maneuver on the part of Blizzard. I don’t like to point out when they utterly fail at something but I believe in my heart of hearts that this is an error that really, a blind retarded chimp with only one leg skiing down the black diamonds could have [...]

Just a quickie update for those that may have missed it.
Void Shatter (skill: 360) requiring Runed Eterium Rod (Skill: 375) is a bug that is being fixed in patch 2.4.2.  (src)

The author of the video claims that it’s a bug. Yes and no. Essentially this is not a bug but a result of a bad internet connection. If your connection times out but doesn’t completely log you out of the game (something like a lag spike then everything suddenly speeds up to get back to [...]

It was reported as a bug that Tauren Druids (not all druids mind you only Horde ones) cannot cast the Cure Poison spell. They can however cast Abolish Poison and it has been classified as a known bug.
We have bugged this, but as for when it will be fixed, we have no ETA. I [...]

Just two more bugs for the day I wanted to put out there.
Stratholme: Abominations in the last chunk of the instance (it’s an event for the uninitiated) right before you face the Baron are borked.
The event will not continue if it attempts to reset while abominations are in combat. We are aware of this [...]

Now, I’m not sure if this has ever happened before but i imagine it must have. Otherwise this is a pretty interesting and somewhat funny bug.
A little while after Patch 2.4 me and my friends got together for a quickie Kara run to farm up some badges and shards. We get to Shade of Aran [...]

People have been running into this issue since the patch where when they die, they cannot release spirit outside of an instance. Hortus gave a quick workaround you can do to beat the bug or you can wait until they fix it which should be with the next patch (2.4.2)
This is a known issue [...]

I’ve spent most of the day today testing hunter pet aggro .
First let me say that Growl and Charge interaction is not the same as it was in 2.3.3, this is being looked at separately by the developers lolwut. I’m specifically looking at the reports that other pets are not not holding aggro as well [...]

Hortus says that the changes to weapon sizes and shoulders etc are intended (partially as some are legit bugs).
Tauren 2 Handed weapons, Female human and Male Dwarf 1 handed weapons are all intended changes. As I have said before If you do not like it please post in the general or suggestions forum. Posting [...]

People were shocked on Tuesday night (and again last night) when Void Reaver no longer targeted or faced players before launching an orb. There are also reports that invisible orbs are spawning from the ground and that sometimes VR launches two at a time. Obviously this is making the fight more difficult than it used [...]

People are having some major crap-tastic lag in the BGs. This blows, I really miss my PVP. Either way Blizzard’s aware.
We are aware of the high latency being experienced in some battlegroups and we’re in the process of attempting to find a resolution as quickly as possible. We will continue to track this issue [...]

This is an issue Blizzard is aware of, basically some player’s raid info tab is showing the reset for instances being way off. Some people are seeing Kara reset in 2 days, 16 days, and so forth. Here is Drysc’s original post, stay tuned as I will update when the bug is fixed.
There’s an issue [...]

We are aware of issues with the PTR and TTR.
Unable to create new characters.
Unable to Delete existing characters
Unable to connect to the realms
All of these issues are currently being investigated. We have no ETA for their resolution at this time.
Thank you for your patience. (src)
Hey nevermind Hortus fixed it.
Our connection [...]

There happens to be a bug on the PTR/TTR where it will not validate the game version correctly. This sucks because what little testing we’re able to do now as the time grows shorter until release, is going to waste. At least Blizzard is aware of it.
We are aware of the issues with game [...]

Apparently Shiv is bugged on the forums, the devs are working on it now.
I’ve spoken with the devs and shiv not being missed or dodged is a bug and was never intended. The changes to the combat log revealed some problems with how this spell is coded and it is being worked on. (src)

We’re currently seeking feedback on the Lady Sacrolash and Grand Warlock Alythess boss encounter, as well as the non-boss encounters leading up to it. The major bug that was making the encounter more difficult than intended has been resolved.  (src)
Which is awesome right!? But then Hortus shuts us down.
Correction:

Sunwell is going to be [...]

I have seen some pretty nutty things on my brief times in Beta and the PTRs, but this one is hands down the best I have ever seen. Hortus announced that the patch 2.4 PTR would be going down for four to six hours to apply a new build.
The test realms were brought down because [...]
