The site maintenance shutdown for flick has been well advertised and even has a little good panda contest for the likes of me (free users or peraps a gift for a friend). This is probably the finals steps of the migration of services off the Yahoo’s servers, but seems to have taken a day longer than anticipated. The new owners and the flicker team seem to have put a have put a lot in place to make sure this is a seamless transition, including a Known Issues page They warn a few features might take a little longer to bring back on-line. However its return to be up online again has not gone so well for me. I can not upload my photos either with the newer photo uploader.
Or the Old Manual Photo uploader
This hiatus is punching a whole in my 365 project (post a photo on flickr each day this year) but I’m not panicking, I’m patient and I’m sure they will figure it out in time, I also realise PRO member will get higher support, Here is a link to the current status of the scheduled maintence, take the opportunity to go take a few more photos, perhaps enter their good panda contest.
