It appears that seclists.org is offline.  That impacts some security mailing lists like Full Disclosure, nmap-dev, and portions of the Insecure.org site.  We don't know why the site is down, but it appears that all of the message archives are missing too.  More details will follow as we receive them.  If you have any first-hand knowledge about why the site is down please let us know via our contact form.
