I have tried to log it to the server but I get lots of errors, I get Can't reach server, or it gets stuck at logging in, or I get Connection Lost End of stream, and I get something about server out of date. but it was just fine a few days ago

It means the server is temporarily down. The website here isn't 100% accurate. I believe it has a five minute lag? Someone correct me if I'm wrong on that, please. When this happens, it might just be the server restarting. The Mods/Admins are still doing updates for all the pluggins. A little patience for them always helps, as they are constantly busy these days. Hope this helps.

I don't think the server has been down for 5 days

Did you download the latest Minecraft snapshot (12w01a) >_> ?
