There was a huge lag storm last night on my server (Uther)...NPC disappeared, pets froze...everyone stood around. Funny thing that chat works fine while lagging...so the ***** and whine fest began, then everything seemed to right itself. Played for another hour or so without lag and they announced the server was going down.
One funny thing...they began a countdown..."server going down in 4 min", "Server going down in 3:45" etc...they got to about a minute and a half and the message came back, "shutdown aborted". Every began saying, "very funny bliz" and "whew, now we can go do that quest" and wham...server went down. Gotta love it.
