Non-working DNS service on and

I do not know is it the appropriate place to report, but seemingly the following name servers are not answering at all:
2600:3c03::f03c:91ff:fe83:79dd (

# dig +tcp @2600:3c03::f03c:91ff:fe83:79dd
;; Connection to 2600:3c03::f03c:91ff:fe83:79dd#53(2600:3c03::f03c:91ff:fe83:79dd) for failed: connection refused.

2600:3c00::f03c:91ff:fe8c:cf2c (

# dig +tcp @2600:3c00::f03c:91ff:fe8c:cf2c
;; Connection to 2600:3c00::f03c:91ff:fe8c:cf2c#53(2600:3c00::f03c:91ff:fe8c:cf2c) for failed: connection refused.

With UDP, it just times out, so it looks like the name servers are not running.

Thank you for reporting this! It’s fixed now.


@NTPman We also had another server in the last days where IPv4 was working (which we monitor well) and IPv6 didn’t (which we don’t monitor nearly as well). We’ll get that fixed. As @gfk said, thank you for reporting it!
