Ngaambul: Hi hamish_h11,
The cache appears to be in need of owner intervention, or it may not but in the absence of the cache owner performing maintenance and/or disabling the cache to check it out, I'm temporarily disabling it, to give the owner an opportunity to check on the cache, and take whatever action is necessary. Please respond to this situation in a timely manner (i.e., within 4 weeks) to prevent the cache from being archived for non-responsiveness.
Note that HQ use an algorithm to calculate a hidden Health Score for each geocache. A low Health Score provides an indication that the cache may need attention from the owner. Note that it may not be immediately obvious as to why you are being asked to look at your cache but if you can check your cache and once you have maintained it and it's ready to find again then enable the cache.
If you require more time please be sure to post a note (not an email) explaining the situation and how much more time you require. For ongoing issues please ensure you visit the listing and post a new note every 4 weeks to keep everyone up to date, if you do not then you cache may be archived without further note from a reviewer. Caches archived due to lack of maintenance are no longer unarchived and you will need to submit a replacement as a new cache.
Ngaambul - Matt
