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 :)

There was certainly a lot of effort made and money spent to make sure it all
worked.
There was a complete freeze on non-emergency changes for some time.
SLAs were tightened up on support contracts with extra money spent to
provide on-site spares at key locations and extra engineering staff were
laid on.

Where I work we had some involvement in the preparations.

"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 was one day and only people who watched online and neglects the effect
of caching downstream of the BBC, relay through mirror sites and output on
other providers' web sites (e.g. NBC).

In any event most people watched broadcast - the opening and closing
ceremonies were several Gb each, more if you watched in HD X tens of
millions of viewers [just in the UK].
