My relay 'angrykitteh' (the kitten is now quite frustrated!) was blessed and granted the flag 'Guard' by the Directory Authorities as its uptime is more than 8 days and the bandwidth is deemed acceptable and fast enough. Great.
The atlas link given shows a slight peak in the 'Guard probability' but dropped immediately afterwards.
Suddenly, only an hour (or two) after being granted the flag, it was gone!
Here's the consensus now, after I discovered the flag was gone: consensus after my Guard flag disappeared http://s21.postimg.org/6r6kywl5h/2013_12_30_001800_1105x134_scrot.png
Why was the flag removed? Why are some authorities still voting to give me it? What changed?
