@ChrisHannah I've tested and blogged about anchor a bit. It keeps changing track, sometimes quite radically. At least 3 times in the past couple of years. Some of the features were interesting but didn’t hang around. I guess I pay for hosting for longer term security. I also see that old anchor embeds on my blog currently say "503 Service Temporarily Unavailable"...
