I did notice that too, not sure what is going on this time. The server we are on is just us, selfsufficientish.tv and selfsufficientish.org. the other two sites don't get nearly as many hits. I will contact the hosting company and find out what is going on.
I have heard that a huge program can get stuck gigablast or something (Wulf???) this can slow it down, basically its a program that indexes all the pages for a search engine. - There are ways to stop it, I think it might even be illegal to use it or something. Again this is another area I am learning about.
