Additions:

Though the DBpedia RDF Data has always been housed in Virtuoso, which has supported all desired means of access since the DBpedia project began, early DBpedia releases used Pubby Linked Data Deployment services in front of the Virtuoso SPARQL endpoint.
As the project gained traction, the HTTP demands on Pubby's out-of-process Linked Data Publishing services increased, and the natural option was to take advantage of Virtuoso's SPASQL (SPARQL inside SQL) and other Linked Data Deployment features, by moving these services in-process with Virtuoso.

Additions:

The DBpedia RDF Data Set is hosted and published using OpenLink Virtuoso. The Virtuoso infrastructure provides access to DBpedia's RDF data via a SPARQL endpoint, alongside HTTP support for any Web client's standard GETs for HTML or RDF representations of DBpedia resources.

Deletions:

The DBpedia Data Set is now hosted in OpenLink Virtuoso, which provides all HTML, RDF, SPARQL, and other related services. In earlier phases, the server architecture was different, involving several layers between a user's Web or Data Browser and the DBpedia Data. Those layers have now been almost entirely eliminated, substantially improving DBpedia's performance and reliability.
