: Tumblr custom subdomain stoped working I have added my custom .tk subdomain to Tumblr. My DNS setup for this domain looks like this: A - mydomain.tk - xx.xxx.xxx.xxx ; MX

The CNAME looks correct according to Tumblr's support doc on using a custom domain name, and if you're reaching a page on their end (as seen before), it's resolving to their servers.

The problem might be related to the .tk ccLTD: Since its registrations are offered free of charge, spam and phishing operators have historically abused .tk domains - see this and this for more on that. So it might be triggering Tumblr's filters.

There are also significant restrictions placed on using .tk domains by the registry, as stated here:


There are content restrictions for free domains, banning sites
containing sexual content, drug use, hate speech, firearms, and spam
or copyright infringement. Also if a domain's redirect target does
not work (even temporarily) the domain is taken offline. If a domain
violates any of these terms, it is replaced by a Sedo ad page, and no
beforehand warning is given. Expired pages (except for those that
received complaints of content violations) can be reclaimed by
contacting their support system.


Noting the second sentence above, the registry could also take the domain offline if a redirect doesn't work "even temporarily".

So although the problem may lie on Tumblr's end, you might consider obtaining a generic top level domain (gTLD), which are not very expensive at some registrars. They would have fewer restrictions with more widely accepted recognition.
