Anyone who plays World of Warcraft can tell you the game has some issues with its servers. It’s nothing new, as it has been a problem for the game since beta. Though, it did seem as if the game was slowly getting better there for a while (at least for some servers).
Even the low population RP-PvP server, Maelstrom, where I play has its share of issues.
Anyway, the crew at C|Net News apparently thought it was a big enough issue to post two separate articles about WoW’s server problems. You can find them here and here.
