The Tekagis update server has finally been moved to a more stable environment (in other words, off my spare laptop and onto a REAL server!). So the random down times are no more, however the TekagisUpdater.conf file for everyone needs replacing to point to the new server.
A new copy can be found here (this goes in your Freelancer\EXE folder):
http://updates.tekag...gisUpdater.conf
or you can manually edit your existing file and change the line

to
Url = http://updates.tekagis.ca/
