Unfortunately we are victims of our own success. Massive demand from around 35,000 or more readers a day, peaking at about 1300UTC, is putting a strain on our two servers. I am looking into expanding the number of servers and load balancing it all but nothing will happen until early in the new year.
Apologies if you are getting a server busy message but please keep trying as you will eventually get through as shown by those of you who have posted above. Along with the upgrade to the servers there will be a revamp of the layout and look of the site with some interesting new features too.
