Other Information

Since the last few hours, none of my .rf.gd domains are working (as far as i checked). The main one has been linked above. Also I noticed that some other people’s .rf.gd domains were not working too. I think that there is some domain issue here. I know that InfinityFree provides free hosting which is really excellent but it would be appreciated if we could get some more information on the matter.
