Just a quick note to explain what's happening this evening...
You may have noticed that the site's disappeared a couple of times, and it may well do again before the evening's out.
We're carrying out some important upgrades; and unfortunately the window of opportunity to get some crucial bits done opened rather unexpectedly, hence the lack of notice - our apologies for that.
As I say, we may have to do a little more tinkering this evening; but will avoid taking the site offline as far as possible, and we should have everything completed which might require brief outages before morning.
Thanks and regards,
