Are the name servers down?
« on: February 22, 2015, 05:43:31 AM »
As far as I see, the all five DNS servers of Hurricane Electric reply neither to DNS queries nor even to ping. What happens? Are the servers down?

dns.he.net shows limit of 1 domain instead of 50 it used to be.

Edit: Seems to be fixed now.

ns3.he.net seems to take a while to respond to queries (and only over IPv4).

;; Query time: 6 msec
;; SERVER: 216.218.130.2#53(216.218.130.2)

;; Query time: 7 msec
;; SERVER: 2001:470:200::2#53(2001:470:200::2)

;; Query time: 1508 msec
;; SERVER: 216.218.132.2#53(216.218.132.2)

;; Query time: 1 msec
;; SERVER: 2001:470:400::2#53(2001:470:400::2)

;; Query time: 1 msec
;; SERVER: 2001:470:500::2#53(2001:470:500::2)

As far as I see, the servers reply to DNS queries via IPv6 only.

Seems it is working on/off. Some network broblems perhaps? That domain limit bug seems bit strange tho. Related or not? Anyone seen that happen before?

I'm seeing problems adding a new domain at the moment.

Hours after adding it (with validation), it's still not slaving (other domains seem to be updating).

Perhaps they have temporarily disabled it.

Part of email reply I got from support:

we were undergoing a sustained attack on our regional DNS servers
which were causing geographically isolated issues resolving DNS queries.

The issue appears to have been mitigated but we are keeping an eye out in case it

Few hours ago, I seen the name servers of Hurricane Electric to reply DNS queries correctly but slowly. For now, the servers reply correctly and quickly.
