Thanks for reporting. Would you mind to fix it?

[darthwalsh]

@LinuxSuRen Sorry, no, I'm definitely not able to fix the doc site problem. I don't have access to edit the DNS records that jenkins-zh.cn is hosted in. (I'm not even sure how to buy domains in .cn!)

Does anybody know if the katacoda content was moved elsewhere? It would be a shame to delete both documentation links from the README.

Actually, the katacoda service just turn off. I don't know the reason. So, I perfer to remove the link.
