Development wiki was down

6 January 2013: The wiki should now be operational again. Thanks to those who gave assistance towards its restoration.

26 December 2012: for those assisting with the debugging of the problem, I have attached the text of the python errors we have been seeing (news-20121217-python_errors.html).

17 December 2012: The web interface on, which hosts our development wiki, is down at present. Investigations are continuing but it appears that a system update by the hosting provider may have inadvertently broken our trac installation. There is no ETA on a restoration at present.
