For a few days now, hosting a particular site appeared to be quite stressful for the poor little box. Luckily, macTijn was able to put most of the data behind a proxy, at least saving some CPU for other stuff :)

However, due to being on Digg’s frontpage a few times, it still is a lot to handle: A load of ~70, tons of php processes running, etc. As soon as the link vanishes, everything turns back to ‘normal’. Since the “problem” seems to occur only while on Digg’s frontpage (and with the help of Google), I’ve found some workaround.

It’s basically an htaccess file that redirects all traffic from digg back to their mainsite. Still have to see the side-effects, but at least now the site works.
And! My box is alive :)
