Yes, KeenerTech.com is still owned by David Keener, the technical architect, cybersecurity expert, conference runner and public speaker.
For various technical reasons beyond my control, the old Rails-based site became non-operational when my hosting plan was migrated from CENTOS 5 to CENTOS 7.
I decided this was as good a time as any to move it to WordPress 4.8. All of the old content will be coming back to the site as I have time. That amounts to about 600 blog posts and accompanying graphics, so that’s going to take a while.
