Technical Difficulty at Flickr
Flickr: The Help Forum: [Official Topic] Current Contacts Issues According to a Flickr Help Forum “Your Contacts Photos” in one of the most popular sections of the site may not update for as long as 2 days.
Given the deterioration of updates around contacts and your contact’s recent photos, we’ve taken what might seem like rather drastic action. For the time being, your contact’s recent photos will not be updating. This functionality has been taken offline by the dev team while we endeavour to implement a scalable solution that should improve the situation. We expect that the downtime will be no greater than 48 hours (2 days).
