The Perils of CDNs

So CERN have just held a popular webcast event to announce the latest results in the search for the Higgs. Many of the webcast viewers (no I don't have usage stats) were complaining that the stream was choppy. What I did notice on my laptop (couldn't get near the auditorium) was that the main libflashplayer traffic was inbound from 93.174.99.0/24 VELOCIX-EU - could this be the CDN used by Groovy Gecko?

Not having an onsite mirror though then meant that each member of staff watching was then pulling data *in* to site as the traffic graph shows:



I'm sure this can't be efficient... Ho Hum.
