So there have been a few changes on the TGN server in the past week or so. Nothing that you should notice but hopefully things that will make the site more stable and make it load quicker. The site now does as much client-side caching as possible and also tries to gzip any files that it can. The site now uses an external ad server and the ads are not served from the TGN server any longer. The OpenX ad server is a real resource hog and given that Wordpress is a real resource hog it wasn't a good combination. I've moved some local hobby sites from the TGN server and put them on their own shared server elsewhere. You shouldn't see any changes to the site but it should hopefully be more stable and load quicker.
