I deliberately didn't use the word "mirror" as that sets expectations around offering same features, using same technology, etc. So I meant what I said: there are other SPARQL endpoints that provide live, public access to the dbpedia data. > As for usage levels, the issues have very little to do we sane SPARQL > query and everything to do with crawlers that actually attempt to > perform wholesale imports of the entire data set (many attempt this as > we can seen from the HTTP logs and the payload sizes).

Yes I'm aware of what dbpedia is, and also the challenges of running a live operational service :) I was just curious about usage volumes. We all talk about how central dbpedia is in the LOD cloud picture, and wondered if there was any publicly accessible metrics to help add some detail that.
