Two days? Scheduled maintenance began at 5:45pm PT May 22nd, and it's currently 12:10pm PT May 23rd. We're hours behind (this stuff is tough), but it hasn't even been one day, let alone two.
The linked page says flickr is down for planned maintenance. There's not really anything informative/educational on the linked page. Not obviously anything that "gratifies ones intellectual curiosity" as suggested in the guidelines (https://news.ycombinator.com/newsguidelines.html).
I'm more surprised that Flickr is still running. Is there a reason to still be using Flickr? I know they allow higher-quality image uploads. Is that what keeps people in the community?
