There is not a big spike in multicast traffic as there was on 9/11/2001.
NASA TV multicast only has reports from 3 viewers at present, which
a total viewership of 10 or less.

As time goes on, I hope folks that show unusual traffic levels (on both
sides; eyeball networks and content networks as well as transit
will send pointers to me that I can share with others. I am very
interested in flash crowd situations and how to mitigate the problems
associated with them...
Historically providers have been reluctant to provide that level of
detail concerning traffic levels. A few providers, generally smaller
ones, do make MRTG graphs available. Once in a while a provider will
announce they had X Peta/Terrabytes of traffic for some time period.
But most prefer measurements which can not be correlated with revenue
(e.g. packet drops, latency, jitter, availability, etc).
I didn't see any noticable change on Abovenet/MFN's public MRTG graphs
at MAE-West/MIX-West. Keynote/Matrix public data show no visible
of the web sites they measure. They may have some private data which
shows more details.
Of course, NASA is a US federal agency, so you can always try the
of Information Act (FOIA). But they have other things to do today.
