Yes. That's the most pleasant problem you can imagine ;)

However, openSUSE isn't the first that had this problem. 

Someone from a big german freemail provider once told me that several 
companies advertising in their newsletter called them saying "we are 
DoS'ed", got the reply "no DoS, traffic!". Then the companies _begged_ 
not to send out more newsletters ;-)

BTW: A variant of DoS-ing a website is DoS-ing a call center - one 
company managed to have this two times, seems they hadn't learned from 
the first newsletter sent out...

BTW2: They already give out "surviving extremely high traffic" guides in 
advance, but sometimes it doesn't help.

Nobody will object, I guess ;-)

My proposal:

Run a   wget -r   over the whole wiki (excluding index.php) daily.
In case of problems, you can switch to that copy. This clearly reduces 
the load on the server (static files vs. "PHP + database + iChains") 
while still serve all information.

The only thing not working will be editing of pages, page history and 
alike - but that hits only a low percentage of visitors.

Sounds much better than having a single "we are offline" page, doesn't 
it?

Yes, it would really be nice if someone can them make available.
