NetBSD.org outage 2017-01-16


January 16, 2017 posted by Taylor R Campbell

[Update, 2017-01-16 20:48 UTC: All issues have been resolved and NetBSD.org should be functioning normally now.]

As some of you may have noticed, the netbsd.org DNS records are broken right now. Two independent incidents caused this to happen:

  1. UC Berkeley stopped providing secondary DNS service for netbsd.org at adns1.berkeley.edu and adns2.berkeley.edu on a few hours notice, before we had time to update the NS delegations in the ORG. zone. [Update, 2017-01-16 20:48 UTC: The Berkeley network administrators have graciously restored service until we can update our NS delegations. Thanks, Berkeley—for doing this on a US holiday, no less!]
  2. The network hosting our primary nameserver ns.netbsd.de went offline at around 14:00 UTC for reasons unknown. [Update, 2017-01-16 20:48 UTC: The network and ns.netbsd.de are back up.]

We have sent a request to our registrar to update the delegations to make ns.netbsd.org primary and ns.netbsd.de secondary. We asked them to expedite the process, but owing to the weekend, when the humans who process these requests are off work, it may take another day for that to take effect, and another day after that for the cached TTLs on the old NS delegations to Berkeley's nameservers to expire.

As a provisional stop gap, if you need access to the netbsd.org zone and you can prime your DNS cache with manually entered records, you can prime it with the following records to restore service at your site:

netbsd.org.     86400   IN      NS      ns.netbsd.org.
netbsd.org.     86400   IN      NS      ns.netbsd.de.
ns.netbsd.org.  86400   IN      A       199.233.217.200
ns.netbsd.org.  86400   IN      AAAA    2001:470:a085:999::53
  

(Presumably if you are reading this you have some DNS records in the netbsd.org zone cached, but they will eventually expire and you may need some others.)

It should be noted that Berkeley's NOC was checking email on a national holiday, and got the zone live again once we contacted them. They said the original deletion was a mistake. We appreciate their quick response to get this sorted out.
