Hi,
I'm failing to resolve the domain from various other locations.
In particular, a query from NS records gives 4:
kaist.ac.kr. 7200 IN NS ns.kaist.ac.kr.
kaist.ac.kr. 7200 IN NS ns1.kaist.ac.kr.
kaist.ac.kr. 7200 IN NS dns180.kaist.ac.kr.
kaist.ac.kr. 7200 IN NS dns181.kaist.ac.kr.
but neither dns180 nor dns181 responds.
In addition to the DNS issue, if you look slightly further back in your
status page, you'll notice that the mirror has been reported as
increasingly out of sync, and was approximately 2.5 days behind the
last time we were able to successfully contact it (2025-07-17 13:45:52
UTC).
Regards,
Adam
