The following trackers have changed in some way compared to the tracker list. The "Not working" once, might just be under schedule or actually down (15-05-2015). Out of function means they do not respond if you try to enter and the security once, may be under attack or send malware to the users on it.
(Only level 2 trackers and up to 10)
