As of today, I am no longer using TekTonic to host my website, and in fact I can no longer recommend their services to anyone else. The performance on my virtual private server was never great, but it was generally adequate. But in the last few months, the server has slowed to a crawl for interactive login sessions (SSH). The TekTonic staff stopped responding to support tickets, and their customer community forum mysteriously stopped working during the middle of all my problems.
Eventually I had had enough and decided to host my website on a spare computer I have at home. So this site is now running on my Dell PowerEdge server, which seems to be mighty fast and working very well. It’s being hosted through a commercial-grade cable modem provided by Cox Business Services. (The small office cable modem service allows me to run a server: normally that’s prohibited for residential customers.)
