Below is a graph showing traffic to the website from a week before the Pope Benedict XVI's announcement of his resignation through the a week after Pope Francis was elected. It'll give you some sense of the jump in traffic.
The website had a few breakdowns - some from sheer volume and some from a weather related power outage. But overall it has been going well.
Over the coming weeks things should settle down to normal. Although if 2005 is any indication, the new "normal" will be a good bit busier than before - I suppose from folks discovering the website due to the events just passed, and then coming back.
