Earlier today 'xserve', the server that hosts www.blender.org, mediawiki.blender.org and orange.blender.org was experiencing load problems and was unreachable for a while. Usually these problems are caused by people who are trying to 'spider' a website for offline browsing. Measures to throttle the maximum number of connections are being taken so hopefully this will soon be a thing of the past.
Anyway, to whoever jumped on his bike to ride to the server location facility today (Ton, Marco, Stefan?): thanks for bringing xserve back to us!
