We owe an apology for the unavailability of the web address for over a week towards the end of January. Although website was still accessible using our alternative (non-preferred) address - it was a very inconvenient situation.

The problem was that the domain name registration expired. The normal chain of communication for renewal reminders had failed because of the untimely death of the Internet adminstrator at the University of Sheffield. Unfortunately, supplying the paperwork required by external agents to prove the change of personnel delayed the reinstatement of the address. They also levied a hefty fee.

The address has now been renewed for five years, and we are assured that this situation will not happen again (fingers crossed!).
