As many of you may have notice, *.limesurvey.org was offline for about 7 hours today. *.limesurvey.org was out in general, including the home page, forums, bug tracking, documentation, and source code at various times. For some of you, it may still be out.
The core problem is with the DNS routing tables of the Registrar. The hosting site (e.g. servers and content) appears fine. The Registrar is well aware of the problem and working on it, so hopefully LimeSurvey will be back up to full speed soon.
