Apache OO will use Apache Infrastructure and Mirrors (many the same) and having someone take

(For historical reasons, too lengthy to explain, download.services.openoffice.org hasn't been
the root of the mirror network either.)

IMHO the plan was to shutdown the "download.services.openoffice.org" as 
it is hosted by Oracle. Therefore the default downloads were stopped to 
go to this server but changed to your server.

However, it seems that the Oracle server is still working. Strange.
