Flickr has finally acknowledged that their new software update on their web site has broken photo uploads. Flickr Help Forum user comments.
Update: Official Flickr Forum thread on the upload failure. Apparently Flickr released a new “auto upload” feature in their Flickr apps that attempts to upload every picture on your device, by default (even if you do not want it uploaded). It seems this has overloaded the Flickr network (duh!) and Flickr was unprepared for the deluge they themselves unleashed as every device attempted to upload massive numbers of photos.
The symptom is that photo uploads time out – and you are unable to upload photos. Obviously, uploads work for some, but also did not work for many.
There are some neat features in the new software including automatic tag generation (for some of my photos, it did a surprisingly good job), and their new “Magic” album that automatically organizes photos by subjects. (It works really well!)
