Now that things have settled down, I'd like to address what happened during the
|
||||
[jenkins-ci.org DNS outage I discussed
|
||||
here](https://groups.google.com/group/jenkinsci-users/browse_thread/thread/b1015d6efd53343f#).
|
||||
|
||||
Long story short, some poor assumptions caused a lot of trouble while switching
|
||||
registrars away from GoDaddy.
|
||||
|
||||
|
||||
----
|
||||
|
||||
First let me explain the motivations for moving from GoDaddy: aside from the
|
||||
SOPA issue, I've *always* hated dealing with GoDaddy. The have had an
|
||||
absolutely **shit** product for a long time, but as a long time customer,
|
||||
momentum was quite a limiting factor. Before my involvement with the Jenkins
|
||||
infrastructure, I would have only used GoDaddy once or twice a year.
|
||||
|
||||
Since becoming the driving force behind a lot of the Jenkins back-end, I've had
|
||||
to deal with them once or twice a month, and everytime I would be bombarded
|
||||
with upsells, ads and other shit that I wanted no part in. With the renewal of
|
||||
jenkins-ci.org coming up in January, it makes sense to switch registrars before
|
||||
I renew the domain for 5 years (which I will be doing).
|
||||
|
||||
The SOPA boycott is just gravy on top.
|
||||
|
||||

|
||||
|
||||
As for the "DNS debacle", here's a quick bulleted list of what happened:
|
||||
|
||||
#### The Negative
|
||||
|
||||
* Jenkins used GoDaddy's DNS service, when the GoDaddy side of the domain
|
||||
transfer was complete they canceled the DNS service and seemingly zeroed
|
||||
out all our DNS records.
|
||||
* The `jenkins-ci.org` nameservers, which are generally copied over when
|
||||
switching registrars, were set to GoDaddy's nameservers prior to the transfer
|
||||
(mistake on my part).
|
||||
* What I had assumed would automatically take effect once the transfer was
|
||||
complete on Namecheap's side, did not take effect. In fact, somehow the data
|
||||
I had entered in was obliterated when GoDaddy's nameservers were copied over.
|
||||
* I'm not good at writing zone files, and the most subtle mistakes were easy to
|
||||
slip past those who I asked to review them. Zone files are the devil.
|
||||
|
||||
Instead of focusing too much on the colossal screw-up, I'd like to focus more
|
||||
on what positive has come out of the situation.
|
||||
|
||||
|
||||
#### The Positive
|
||||
|
||||
* `jenkins-ci.org` is now with a registrar that isn't commonly accepted to be
|
||||
"freakin' terrible"
|
||||
* To mitigate the downtime people were experiencing, I quickly set up what I
|
||||
presumed would be a temporary nameserver on one of our machines colocated
|
||||
with the [OSUOSL](http://www.osuosl.org).
|
||||
* Instead of taking that nameserver down, I've actually promoted it to become
|
||||
`ns1.jenkins-ci.org` which is wholly powered by [our Puppet
|
||||
manifests](https://github.com/jenkinsci/infra-puppet/). Now anybody in the
|
||||
community can submit a pull request to add records to [our zone
|
||||
file](https://github.com/jenkinsci/infra-puppet/blob/master/modules/jenkins-dns/files/jenkins-ci.org.zone) and we can
|
||||
approve and deploy it all from GitHub via Puppet.
|
||||
* While working on DNS, I noticed that `iptables(8)` wasn't properly configured
|
||||
on some of our hosts. We've since bundled the [firewall module from Puppet
|
||||
Labs](http://forge.puppetlabs.com/puppetlabs/firewall) in our repository and
|
||||
set up the appropriate rules on all hosts to lock them down.
|
||||
|
||||
|
||||
I could vent about the idiocy of the DNS system, how much I abhor GoDaddy, or a
|
||||
myriad of other issues that had to be resolved in these past two days, but that
|
||||
wouldn't be very useful.
|
||||
|
||||
Despite the amount of time consumed in the affair, I think the project comes
|
||||
out ahead and stronger, and at the end of the day that's what is really
|
||||
important to me.
