You may have noticed some problems with the site today, which have been caused by infrastructure changes at my hosting provider. The problems manifest themselves when I have ‘friendly URLs’ turned on, so for the moment I have turned them off. This means that links to specific pieces of content are temporarily different (and uglier) than usual. I am working to fix this and will post updates (probably won’t have time to work on it for a day or two).

Update: I have reactivate the ‘friendly URLs’ as the problem appears to be resolved. I’ll keep an eye on it.
