Strange issues... Anomaly)

[Nadir Aliyev]

Hmm interesting that, sometimes dns query can get normal result. 

But sometimes not.

 

Its bind bug or godaddy's problems? Any ideas?

 

But interesting that I detected this problem no goddaddy's servers to.

For example from following korean site I cant get normal results.

 

# nslookup kotra.or.kr

;; Got SERVFAIL reply from XXX.XXX.XXX.21, trying next server

Server:         XXX.XXX.XXX.22

Address:        XXX.XXX.XXX.22#53

 

Non-authoritative answer:

Name:   kotra.or.kr

Address: 125.131.31.31

 

 

I don't know maybe problems like that have many, but absolutely no logs
about errors. Timeout or servfail. Current time I know that I can get result
from godaddys nameservers.

 

And some tests with godaddy here:

 

dig +dnssec @ ns51.domaincontrol.com. replacementservices.com.

; <<>> DiG 9.7.1 <<>> +dnssec @ns51.domaincontrol.com.
replacementservices.com.

; (1 server found)

;; global options: +cmd

;; connection timed out; no servers could be reached

 

 

 

traceroute to ns51.domaincontrol.com (216.69.185.26), 64 hops max, 40 byte
