One of our concerns in covering today's events has been to make sure traffic load to the News website doesn't cause problems for our users.
So far our technical team have successfully made sure it hasn't, but traffic certainly has been heavy. By lunchtime we'd already had about the same number of page views as we'd normally get across a whole 24 hours. The top story alone had over three million page views, several times more than on a normal day.
According to our traffic stats monitor, the second most read story so far has been our round-up of travel advice and information from all the main airports. We've given this a lot of prominence and had people dedicated to updating it all morning, helped by all the readers' on-the-spot accounts which we are getting - it looks like that has paid off as our users are clearly looking for this information.
UPDATE 1530: Anthony Sullivan, who helped develop our traffic stats monitor, adds that it has been showing traffic levels between 60% and 70% above average today - the largest volume since July 7th last year.
UPDATE, Friday morning: Yesterday turned out to be one of our two or three biggest days on record for traffic, with 6.8m unique users and 50m page views. The most read stories were the main writethrough on the terror alert, airport/travel info and pictures. Audio Video usage was also very high - particularly the live stream of News 24 coverage - and we received about 10,000 emails from users.
