Update 4 May 2014 - The first physical stage of this cache is now accessible again. Checked today and all present and correct
Update 17 September 2013 - Please note that although I'm enabling this cache, the first physical stage is still not accessible. If you want to do the cache for the time being, please email through my profile with what you would do there, and I will send you details to take you to stage two. All other stages now replaced and ready to go, although the format has changed slightly since the cache was originally set. Note the new attributes, and if in doubt about what is required please ask before you go!
