some time ago the decision was made to move rack #1 of the datacenter to another location. After investigating the possibilities, we have decided to relocate to the front room (FR on internal plans).
Due to the shared circuit of the kitchen and current outlet, as well as the already present dual outlet in the front room, the unused circuit C4 has been re-wired to the new location for the rack. Additionally, the fusebox has been equipped with 3 outlets from C4 of which one runs the lighting, another one runs the fiber/ethernet bridge and the third outlet poweres the rack.
Please note that the physical migration of the datacenter will cause some downtime for the services that depend on resident servers. We will update the website to warn of the downtime, as soon as a definitive time and date are known.

As magnetic fields on the sun rearrange and realign, dark spots known as sunspots can appear on its surface. Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours. It has grown to over six Earth diameters across but its full extent is hard to judge since the spot lies on a sphere not a flat disk.
The spot quickly evolved into what’s called a delta region, in which the lighter areas around the sunspot, the penumbra, exhibit magnetic fields that point in the opposite direction of those fields in the center, dark area. This is a fairly unstable configuration that scientists know can lead to eruptions of radiation on the sun called solar flares.
The bottom two black spots on the sun, known as sunspots, appeared quickly over the course of Feb. 19-20, 2013. These two sunspots are part of the same system and are over six Earths across. This image combines images from two instruments on NASA’s Solar Dynamics Observatory (SDO): the Helioseismic and Magnetic Imager (HMI), which takes pictures in visible light that show sunspots and the Advanced Imaging Assembly (AIA), which took an image in the 304 Angstrom wavelength showing the lower atmosphere of the sun, which is colorized in red.

it has come to our attention, that there has been lack of support for Solaris on the SPARC platform in recent Asterisk releases. Obviously, Asterisk was intended to run on Linux, and various components such as DAHDI strictly require the Linux kernel (source), however, our experience with Asterisk on Solaris has been outstanding. In 2006, http://solarisvoip.com released a packaged version of Asterisk 1.2 for Solaris/SPARC and some complimentary utilities. Since then, there has been no apparent attempt to provide an updated version. The source code of the 1.6 and 1.8 releases include various fixes and compatibility libraries for Solaris on x86, but not on SPARC.
We have now successfully compiled and are running Asterisk 1.6.24 on Solaris/SPARC, and decided to release probably the last version for this unique platform. Apart from a number of smaller hiccups, such as a SEGFAULT when initiating the daemon with full debugging options and the occasional crash when reloading the core under certain circumstances, the software is fully functional and includes the default and extended sounds in WAV, aLaw, uLaw and GSM formats. We have also included MP3 support (LAME) and most of the modules from the Asterisk 1.6.24 addons -package such as cdr_addon_mysql and res_config_mysql.
You can download the package from http://download.pelnet.eu/data/solaris together with an accompanying text file which provides some more detailed info on the build options and parameters used.
