http://answers.gazebosim.org/ seems to be unavailable most of the time for quite some days now. Also yesterday I noticed that all entries have disappeared since the end of 2015.
Are you performing a system change or something causing those issues and is there a chance to restore the missing entries since 2015?
answers.gazebosim.org should be working again. We think that there is no data loss but an old version of the site was working from 8th Mar during a couple of days.
Don’t hesitate to inform us if you see more problems.
Thanks.
