Maybe I am jumping the gun, but I waited several minutes before reporting anything. It seems to me that WebmasterWorld is currently down. I first noticed when the RSS feed on the site of this forum began loading slowly and timing out when it hit the WebmasterWorld feed.
But it seems like it is down from multiple locations.
This is not the first time this popular forum was down, it was also down on November 09, 2005 which lead to the Bot banning and ultimate re-inclusion of the site.
Updates to come in this entry.
Update 9:24(EST): Seems to be back, but still pretty slow and sometimes unresponsive. I am trying to find a thread in the forum with more information, not succeeding yet...
