I guess the tool you are using tries to connect once (since thats normal procedure). DMOZ implemented a load-restriction lately, while staff works on server capacity being increased. That is to provide more percentage of the not sufficient capacity to the editors :)
Stupid thing is that you will get a "server down" each time you dont get a free slot. The server isnt actually down in this case, submitting several requests would show that ;)
(Okay, it actually was down for some hours lately, but this was the first really "down" for some time now)
