635965 - DNS issue with webmademovies.org

Status: RESOLVED FIXED

(mozilla.org Graveyard :: Server Operations, task)

Description

[Brett Gaylor [:brett]]

Hello - we're having some trouble with the development environment we have set up at dev.webmademovies.org - could you check that the *.webmademovies.org is resolving correctly?  Could you restate how the DNS is working for this server?

Thanks for help
Brett

OK, this is just weird...

!!!  wtf did the Dreamhost record come from?

My local nameserver is forwarding requests to Level3... let's check their nameservers:

mbp:~ dave$ dnstracer -s4.2.2.1 -4 -o dev.webmademovies.org

OK, so Level3 has a messed up nameserver.  No idea how that happened or what to do about it.

Yeah, it's been going in and out. Has been for 2 days.

[Brett Gaylor [:brett]]

Ah geez - Dave, this domain had once been hosted at Dreamhost.  I deleted any hosting record over there.  Will this take some hours to move through DNS servers?

Comment 6

[Dave Miller [:justdave]]

We supposedly took it over several weeks ago, and root-level changes are supposed to propagate within 2 days.  I've no idea how the Dreamhost record is sneaking back in somewhere.  Someone has a faulty cache or something.

[Brett Gaylor [:brett]]

K - I'll contact their tech support.  Can you send me a message to pass along?

Comment 8

[Dave Miller [:justdave]]

This wouldn't be a Dreamhost issue, more likely Level3 that has the problem (unless there's other nameservers you know of returning intermittent bad info)

Comment 9

[Dave Miller [:justdave]]

Is this still going on at all?  Everywhere I test from today seems to be getting the correct answer.

[Brett Gaylor [:brett]]

Thanks, Dave - seems to have been sorted.  Appreciate you looking into it again.
