As a matter on interest how long was it? I lost connection about 9:30pm BST and have just come on again at 11:00pm. I had no means of knowing whether this was a short "blip" or the start of another 36 hrs problem as per the weekend.
If there are going to be several in the next few days/week or so it would certainly help if there were announcements. We can then check the announcement board after logging on and this eliminates the awful uncertainty of not knowing if it is a scheduled outage or the start of another serious crash.
