I was on the road today on my bike (rode 600 miles to New York for a rally) and when I arrived here I received 3 alerts from the server (between 8:55 and 9:10 pm eastern) that the web server was down. I logged in to the server to find that it wasn't actually down but was running extremely slowly. There were several apache processes that were locked up loading up the server. I rebooted the server at that point and it should be better now.
I have also been working on slow performance from the new server for the last couple weeks. There seems to be a bug in one of the newer upgraded versions of either apache, php, freebsd, or the libraries. I am working on it with our freebsd guru as best I can. I hope to have it back fully functional soon.
Later this year we are also going to be installing additional servers behind a load balancer to deal with the loads we'll be placing on the site this winter.
