The World Cup: The internet gets through
How did you watch the England match yesterday? If you watched online, you were part of a record-breaking crowd.
With the match being played in the afternoon, the BBC was expecting exceptional levels of traffic as people at work accessed the Sport website or the iPlayer.
And so it proved - as well as office workers, a number of schools watched online. My son returned home with tales of electronic whiteboards used to show the game.
At the peak, the BBC says there were 800,000 concurrent streams during the England v Slovenia game - that's the peak number watching at any one time, and will be much lower than the figure for unique visitors.
That smashed the previous record set, ooh, ages ago on Monday, when there were 355,000 concurrent streams for coverage of the World Cup and Wimbledon.
There were other reports of record traffic; the internet service provider Demon says there was a 55% increase in internet traffic during the match, while Easynet put the spike in traffic at kick-off at 226%.
This was not just in the UK: there are reports from across the Atlantic that web traffic to news sites hit record levels as the USA played Algeria.
Arbor Networks, a firm which monitors the internet, says it saw Flash traffic peak at more than double normal levels, and Flash, as it points out is just one small part of World Cup video.
By the way, for evidence of how excited some Americans now are about the football, take a look at this clip.
But despite this huge flow of video, the internet stood up to the strain. Interoute, which runs Europe's largest fibre-optic network, says there was no mass surge in internet traffic overall. It speculates that routine net activities, such as web browsing, fell away.
True, some people reported problems viewing the video streams - one viewer told me that his reception of the BBC stream was 13 minutes behind the TV by the end of the match.
But the real loser has been Twitter, which has come under unprecedented strain during the World Cup.
A site which measures the availability of services like Twitter shows it suffered significant downtime on Wednesday, one of a number of incidents over recent days.
All in all, however, a day when the internet proved once again how robust it is. A few months back, Craig Labovits of Arbor Networks told me that the running joke in the engineering community is that the internet is always on the verge of collapse.
Fingers crossed, it looks like it might just cope with the global online event which the World Cup has become.
