    I updated one of my servers last night to 11.34.0 (build 2) and I have a couple customers call and tell me that things have broken on their websites. After some investigation it appears their zone files were overwritten with what looks like default zone data.

    Things like MX records, custom cname entries, etc are all just gone.

    Has anyone else experienced this? I know it happened to at least 5 customers on that box, and I'm sure more that just haven't realized it yet?

    This thread is referencing the creation of proxy subdomains. It shouldn't affect MX or custom CNAME entries. If you are seeing those changed, please open a ticket as there is something else going on.

    Re: Autodiscover dns records

    Thanks nick

    Just had a new issue where one of my DNS zones had a duplicate entry (2 extra A hosts) pointing to the local WHM server. I'm sure this won't be the only one.

    I'll go ahead and open a ticket because I know for sure that two of the users affected so far were cname and mx records.

    One was using the google mx records
    One was using custom cnames to point their site to a photo site

    And the last one was a bit more interesting. We had transferred his site from server "A" to server "B" some time ago, but apparently forgot to remove the account from server "A". Now, server "A" is the one that had the 11.34 update, and his whole zone file was set back to point to server "A". So his site, e-mail and everything was shot back to the original server.

    I don't yet know how many other customers were affected by this since I didn't have backup zone files.

    Re: Autodiscover dns records

    They were identical. Have a custom service pointing to an IP

    The example was

    service.customer.com IN A 1.2.3.4 Working up until the customer called me

    Logged in and checked DNS records for customer.com it had 3 A records for service:
    service.customer.com IN A WHM.IP
    service.customer.com IN A WHM.IP
    service.customer.com IN A 1.2.3.4

    service.customer A record added twice automatically post upgrade.
    Only way to find out was that the service was denied and pointed to local WHM IP.

    This sounds more like a dns clustering problem. I'll check your ticket after I get some sleep. Hopefully it will already be worked though when I at look at it again.

    No. All of those were there - autoconfig and autodiscover created pointing to WHM address also.
