The Sysadmin team worked hard on several fronts making sure several services were properly installed and configured for GNOME users. During this year the extensions.gnome.org website was launched, the sysadmins took care of it preparing a virtual machine which is currently hosted at the Phoenix's Red Hat datacenter.
The GNOME Infrastructure discussed and lately agreed on installing what will be the substitute of JHBuild, OSTree. The original proposal came from Colin Walters, who was given access to a virtual machine for starting his build tests.
A Piwik istance has been installed to track the statistics of multiple GNOME websites including www.gnome.org, planet.gnome.org, news.gnome.org and projects.gnome.org. Also the GNOME Sysadmin team received the Class 2 level SSL certificates from StartSSL, several GNOME services and websites were covered by SSL and the expired certificates were removed and replaced.
In regard to our Wiki, the machine that was hosting our MoinMoin istance became too old and many existing problems were found (including Out of Memory issues taking down the Wiki for several hours), live.gnome.org was then moved to its own virtual machine and assigned a good amount of CPU and RAM covering the present and future loads.
Two more virtual machines were created during this period: one (bugzilla-new) to start testing the latest Bugzilla 4.4 release and the other (restaurant) to replace our main Postfix host that was standing on a very old machine ready to be retired.
In addition to that the GNOME machines hosted by Canonical were moved to another datacenter and upgraded to the latest available Ubuntu's LTS release.
Lastly our main database host (drawable) had a RAID failure back in June 2012, the failed drive was replaced successfully and the databases were migrated back from the host where they were temporary hosted.
