During more than one month my blog was down. I had several complains about the missing OpenOffice.org Eclipse integration update site. This is mainly due to my ISP for not warning when they unactivate an account. In fact Free.fr as unactivated my account due to too many spam comments in the database.
On top of that, I had no internet connection during the same time and it was hard to manage these two problems at the same time with the ISP.
Now everything is up again but you can also get the update site at this address: http://api.openoffice.org/Projects/EclipseIntegration/dev-update/site.xml.
