For a long time the video links on
https://commons.wikimedia.org/wiki/Wikimania_2005_Presentations have
been broken, pointing to some abandoned server in Amsterdam. It looks
like the videos were never uploaded to Commons, perhaps due to file
size limits or other limitations in place at the time.
I just noticed that the Wayback Machine has copies of most of them:

Any takers for getting these up on Commons? I noticed that
unfortunately files >100MB seem cut off including the higher quality
copies, so unless there's other copies of these around, it'll be hard
to recover them. (This may be a limit on archive.org's crawler, or it
may be a limit on how much content they serve. I suspect it's the
former, but will ping them as well.)
