Yep, good catch Greek, I didnt check news!
Cool Beans! Boy I wish these were all this easy:
There’s several things going on at the moment, it seems:
Spammers are trying to use plone.org as a redirection engine (fixed)
After removing the spam, we have an excessive amount of “not found” 404 pages, so we had to disable the helpful error message for a more CPU efficient version (in place for now)
Several individuals had started aggressive download (wget) scripts on the web site (they now get a nice firewall message)
There was a very aggressive RSS aggregation script hitting all our RSS feeds every few seconds, originating somewhere in China (now blocked)
A Russian IP posing as a Microsoft search bot was continously fetching non-existing pages
When it rains, it pours. 
We hope to have normal service restored shortly, and apologize for the slowness. If there are short outages, it is because we are adjusting the site configuration to better cope with the current abuse.
Many kudos to the people helping out in getting the site up on its feet again: Alec Mitchell, Wichert Akkerman, Geoff Davis, Alan Runyan.
