We're working on migrating to a different host running Mailman and I need some help from you before we do that since we don't control the domain.

1. Please update the A record for lists.jenkins-ci.org to point to 140.211.9.53
2. Add an AAAA record for lists.jenkins-ci.org to 2605:bc80:3010:104::8cd3:935

3. Create the following TXT record: "v=spf1 mx include:_spf.osuosl.org ~all"

This is the first step which will move the web frontend to use our HAProxy proxy. We already have it setup on HAProxy so these changes can be made at any time.

Once completed, we'll verify it's working properly and then add https for each domain using LetsEncrypt.

The last step is actually moving the mailing list to the new host which will happen later. We'll reach out when we're ready for that!

Please let me know if you have any questions!

Hi Lance, we acknowledge your email, thanks!

Right now, the new HAProxy seems to answer HTTP/503 errors: is that expected?

```

$ curl -v -H 'Host: lists.jenkins-ci.org' 140.211.9.53

* Trying 140.211.9.53:80...
* Connected to 140.211.9.53 (140.211.9.53) port 80

Apologies! I somehow missed getting that domain added. It should be working now.

curl -v -H 'Host: lists.jenkins-ci.org' -k https://140.211.9.53 is now answering properly for me!
