I'm wondering what sort of traffic goes to ISC servers, could this be made public, possibly mrtg graphs :)
In normal operation F in Auckland answers a couple hundred queries per second at peak, corresponding to a client catchment of most of New Zealand's Internet (excluding 4648, who we have no way to reach at present). F as a whole (all nodes) normally answers a little under 10,000 queries per second. The Auckland node is engineered to deal with flash crowds (e.g. wildfire lookups of "WORKGROUP" by new and exciting windows worms) and denial-of-service traffic which fills the wire, which in this case means the two 100M connections to the APE. Short-term incidents which exceed the usual query rate by a factor of 10 or more are not uncommon (F as a whole saw around 80,000 queries per second for a short period about three weeks ago, for example). Graphs for the last 24 hours or so are attached. Real-time graphs are published through ISC's OARC (https://oarc.isc.org/) where work is also taking place to do fine-grained instrumentation of F-root traffic globally under a US NSF grant that ISC and CAIDA were recently awarded.
