Works here (25 hops away), but takes quite a while to resolve. Probably
some of their DNS servers is not reachable maknig DNS a bit shaky..

Might also be that your DNS server rightfully does not like illegal CNAME
chains. The site uses a CNAME of a CNAME of a CNAME of an A. The DNS
standard only allows a single CNAME in the chain. And the fact that the
middle of these CNAMEs uses a very short TTL (300 it seems) does not make
things more reliable either..
