Olympics viewing on the internet

http://www.theregister.co.uk/2012/08/14/bbc_olympics

"In total the corporation shifted 2.8 petabytes of data [...] the flow
peaked at 700Gb/sec."

From a quick measurement of data consumed by the Olympics iPlayer, it
seems to be approx 192kBps

so ...

2.8PB/192kBps represents a total of 508 years of viewing, or 4.4 minutes
per person in the UK.

That figure seems rather low. I watched some Olympic events via the BBC
Sports pages, and in full screen mode it was averaging about 3.5Mbps.

Agreed. 192 kbps sounds more like a good audio stream. The iPlayer web site
has a speed test function which shows TV options as 500, 800, 1500 and 3500
kbps. The latter is the HD stream you were watching and most viewers with
decent broadband would get 1500 as the norm.

You forgot all those using proxy servers to view from outside UK.

Unless they're caching proxies, they'll be included won't they? It's all
on CDNs but I presume they give auntie stats for all downloads? Anyway
the more people the fewer minutes per viewer ...

When I tried it this morning, it was bursting to 240-250kBytes/sec with
close to zero inbetween the bursts, so I did a mental averaging out over
a few minutes to get to somewhere under 200kBytes/sec

Just measured the data during half an hour of watching fullscreen (at
1366x768) and it took 276MBytes, so actually averages out at
157kBytes/sec or 1.2 Mbits/sec

Note that I was quoting kBps not kbps ...

I have watched full screen and I don't even have 3.5Mbps (or half that!)
so something does not add up (or its adaptive)

The 2.8PB was done in the busiest *day* not the total for the whole
fortnight.

Does anyone know if the guys at Telehouse were on a nice little earner
on account of all that extra traffic (like the bonuses for workers on
the tube, buses, trains etc)? I am sure they could have argued extra
traffic must mean they have to take extra care not to trip over and pull
out a peering link
