I have returned from vacation to find a large number of my Flickr uploads apparently wiped out. Has anyone else experienced anything similar? Apologies if this is a widely known phenomenon, but I've been out of touch. I know Flickr had a datacenter migration recently, related to the Yahoo! acquisition, but this seems to be a fairly major disruption, if my experience is common to others.
UPDATE on 11th July AM: The problem seems to have rectified itself. The approximately 50% of photos which last night appeared as broken links have now magically reappeared.
