In our office we only see things that go wrong, because we get complaints, so it seems to me as if it's frequent and too frequent. But I can't put that in the context of all the access requests that we never get a complaint about. The system gets 25,000 requests a year and we get 1,500 complaints, so I have a little window onto what really goes wrong.
On October 2nd, 2006. See this statement in context.
