The list seems to miss all the SWI-Prolog endpoints for some reason,
e.g. http://www.ckan.net/package/jamendo-dbtune
That's because they were all 500 yesterday.
From what I've seen, at any given time 10-20% of the LOD Cloud SPARQL
endpoints seem to be down ...
Best,

The real news here is that we now have more than 100 live SPARQL

Very nice list. Good to see that there are a few endpoints around.
This entry seems to be listed twice:
http://api.talis.com/stores/bbc-backstage/services/sparql
A while ago I wrote a simple script for finding endpoints, which had
the
output listed below. It may or may not be useful for you. There is no
guarantee that those endpoints are still working (and of course
there is an
overlap with your list). Last time I checked, some of those
endpoints didn't
really support SPARQL (failed on simple SELECT/CONSTRUCT/ASK queries).
Kind regards,
Jens

Richard,
Also note: http://www.delicious.com/kidehen/sparql_endpoint . I've
collated endpoints here for many years. This bookmark is also what we
used re. SPARQL endpoint oriented DNS-SD instance setup.
BTW:
lod.openlinksw.com/sparql (missing from the list above) is a massive
endpoint (as you know) that hosts as much of the LOD cloud we have been
able to get our hands on. That said, I don't necessarily know how it
could be accurately depicted in a cloud pictorial without said pictorial
including data about database size. Our last count was 17+ Billion Triples.
Another confusing (re. pictorial construction) is:
http://dbpedia-live.openlinksw.com/sparql (where the DBpedia Live
edition is being hot staged).
