Yes I'm getting that too. It leads to https://thewhitetulip.gitbooks.io/webapp-with-golang-anti-te...

The author probably forgot to edit that file and those are default links of the template he used.

Yes, that is my Go book. I copied the template from that book thats why it happened

So is the YouTube link, the leanpub link and the code tasks link.

I can't reach anything under gitbooks.io at all. Some GDPR paranoia thing again? It would be lovely to get an HTTP 451 at least.
