[tor-relays] Loss of Stable flag

Hello to all relay operators!

My relay Deepsky (09A70E396DE93F54D4541BBB0EC8E2B23761F34F) has not been receiving the 'Stable' flag from the DA consensus. Up until recently (the past month or so) it had been assigned the full complement of flags. Nothing has been changed on the server and I am not aware of any issues. Would any of the directory authority operators be able to shed light on why some of the DAs are not assigning it the flag?

Thanks!
