Website wasn't reachable :-S

Sorry guys, apparently the website wasn't reachable since yesterday but I only noticed it just now. For some reason the server thought there was 0 gigabyte of memory available which obviously isn't large enough to handle any kind of process :-P. I just restarted the server and everything works again. In the mean time I'll set up some notifications so that in the future I can act quicker. Again, my apologies.
