As you’ve noticed, there was a server crash and the site has been restored from a back-up. I’m told that the site is on a new server. The recurrent down-time leading up to the crash was presumably related. Lost in the backup are my post on Mann at the NAS panel, my update to the Cook et al. post and all comments on Cook et al. and Mann at the NAS panel. My apologies to all. It has nothing to do with us but with the webhost provider. Hopefully the new service has been upgraded in the process.
