Anyone meet DNS fail translate repo.or.cz

ALL:
       I can't access repo.or.cz from yesterday.
       DNS can't translate repo.or.cz.
       Even
       http://www.dnswatch.info/dns/dnslookup?la=en&host=repo.or.cz&type=A

       It also can't recognize repo.or.cz.

       Anyone meet the same problem?

best regards
