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?

Each authority votes on what they think the proper flags are for your relay.

Currently it seems 5 think angrykitteh should have the Guard flag, and 4 think it shouldn't yet. Depeding on which authorities manage to vote for which consensus, the flag might end up being set in the consensus or not.

I suppose in a while the remaining 4 authorities will also conclude that your relay is sufficiently stable and give you the guard flag.

I am in the same situation. My relay is jobiwan. Guard flag has been wild lately.

I believe this happens when your bandwidth is just about enough to be guard. The authorities vote 4 against 5 or 5 against 4 and small fluctuations in your consensus weight fraction can flip the balance.
