Imagine if Blizzard cared about the people who play their game.
All it would take is a quick blue post. Hey guys sorry we ran into some trouble, heres the problem and we are working on a solution.
I bet the feed back you got would be much better, as most people like being informed on what is going on.
Did you mean this blue post?
[Burning Crusade] Scheduled Maintenance - 05/27 - Support / Service Status - World of Warcraft Forums (blizzard.com)
Granted they don’t say why, but you could’ve known last night.
WTF … now i am angry … the muppet at blizzard … wrecking my fun .
So they posted the 10am extension 15 hrs ago when it was just extended? Seems sus, also still not indication as to why the down time was extended?
lol the fact that they just edited that tho to say 10am and no answer for it that is the problem
Hey folks,
We received word last night that they would be doing maintenance this morning. So, we went ahead and posted the originally scheduled time as usual.
This morning, during maintenance, a crash was identified that was preventing realms from coming back online. The WOW team asked that we communicate an extension for maintenance so they could identify and fix the crash.
Apologies for the short notice on that extension update. It came towards the end of the scheduled maintenance when the crash was found.
Hopefully things will be back up soon!
Kalviery, I really appreciate the feedback! Thank you very much, see everyone at 10!
Thanks for the update Kalviery. Please ignore all of the negative posts. Some of us understand that sometimes things happen that are out of your control.
No worries! Whenever we have a pre-patch, we expect more of these unusual maintenances. We know that the additional downtime is an inconvenience and try to avoid it.
The WOW team is fixing hundreds of bugs every day, and some of these bugs require the realms to be restarted before they can be picked up.
Sometimes the impact of a bug is small enough that it can wait for a weekly reset, but sometimes the bug has enough impact to merit a quick restart. Today, that quick restart turned out to be a little longer because of the crash that was caught during maintenance.
what were the initial fixes for the maintenance where do you guys post what you are fixing in the downtime?
Not all bugs are publicly commented on, but I’m personally keeping an eye on the Daily PVP Call to Arms quest bug (mentioned here).
They make regular updates to the Hotfix Blog covering some of the more impactful bugs that get squashed:
Realms are back up by the way 
Bruh it’s been (checks calendar) 15 years and the dev team has said they have data from TBC on, so how is this an issue? I’m just confused, a multi billion dollar company can’t hire and pay decent people/wages to ensure you have a good product for the people who have been paying for all this time. Not trying to shoot the messenger, i can’t blame a community worker, i blame the higher ups.
I see this sort of comment a lot and the assumption here is that the technology is the same, so it should be as simple as turning a TBC server back online. This assumption is inaccurate.
Not only has server technology changed over the last 15yrs, the World of Warcraft general infrastructure has also changed. Development involves porting old code onto new systems.
The original game data is used as a reference point, to ensure the new game matches the expected experience. But the technology under the “hood” is all new.
They cover a little of this in the blogs from before Classic launched:
Frustration is definitely understandable though! I hope this info helps shed a little more light on the complexities that are involved in running a live service game like World of Warcraft 
LOL thats cute that you believe it will be up at 10.
Can we also get a quick explanation as to why we had a maintenance to begin with on Thursday after just having maintenance on Tuesday, and will this be a common occurrence?
It’s up now.
I provided that in one of my previous replies:
With realms back online, I’m going to go ahead and close this topic. Thanks again everyone for your patience with todays restarts
