NXDOMAIN/SERVFAIL for google.com from 1.0.0.1 (Amsterdam/NL)

dns

#1

Some time 1.0.0.1 answers with NXDOMAIN or SERVFAIL for exiting domain names.

host -t a google.com1.0.0.1

Using domain server:
Name: 1.0.0.1
Address: 1.0.0.1#53
Aliases:

Host google.com not found: 3(NXDOMAIN)

Using domain server:
Name: 1.0.0.1
Address: 1.0.0.1#53
Aliases:

Host google.com.localdomain not found: 2(SERVFAIL)

1.1.1.1 - works well.

Would you mind trying the dig commands (especially the server ones to determine the colo you are hitting)?
