Is Flickr unblocked?

Today I accidentally opened Flickr and found that almost all pictures could be displayed, except for a few that did not affect browsing, others could be opened smoothly.

I don't know if it's because I live under a rock. Last time I opened Flickr no picture could be displayed. This time I was greatly surprised. I don't know whether this means Flickr has been unfounded by the three letters organization. If so, it is really a very good news.
