How Registrant down affect our DNS?

    Hi everyone,

    Our domain name is back up (including email and web service) after one and a
    half day down. For a City, this is really not acceptable. The reason we are
    down because the Registrant, who own our domain name, had internet down. But
    we host our own external DNS server.

    I would like to ask how this problem happens... and how to work around? Any
    redundant way we can try if we want to stick with that "s_cker"?

    Finally, we may consider to change our domain name... which is already tie
    up with our Active do we migrate from one domain name to
    another one?

    Thank you for your help!

  2. Who's your provider? Does it happen often?

    For a city, I would imagine that you would have your own infrastructure in
    place, with your own Exchange mail server, web server, a fast internet line
    from a reliable provider (not cable), such as Verizon, Quest, etc. Suprising
    to hear a (major?) city is relying on hosting their private and sensitive
    email with some outside source.

    How to prevent it? Go with a reliable provider, or better, as I implied, to
    host it yourself with your own IT department.

    But then again, if a small city, township, borough, etc, budget may not be
    allowing such a thing, which I can understand. But I would honestly consider
    bringing everything in-house for security purposes.

    As for your AD name to be the same as the external domain, no problem, many
    installations are like that. No need to migrate for such a reason. If you
    are experiencing any problems regarding this scenario, please post them, and
    we can offer suggestions to overcome them. They are probably just simple
    administrative tasks needed to be made to accomodate the scenario.

    Hi Ace Fekay,

    Thank you for your prompt response. I am sorry if I misled you.

    Our domain name does not belong to us, and owned by a consultant (actually a
    registrant). We jsut "rent" the name from him.

    We have our own infrastructure such as external DNS (primary), email, web

    Sorry if I mislead you... I should have deleted (including email and web)
    from my first message.

    If the consultant is worth their while, they should have no objection to
    selling the domain to you out right at a reasonable price (2 - 5 years
    worth of rent?).
    If you have your own infrastructure, including external DNS, how did the
    consultant's loss of internet take you down? Is the world looking at
    the consultant as a secondary who is really pulling from your server(s)?
    Is email flowing through the consultant before flowing in to your

  5. Ok, that clears some of it up, but still, it is YOUR or the City's domain
    name, that should be owned by the city. I agree with Grant that the
    consultant should relinquent the name to your city, and registered under the
    city's charter.

    If you have your own infrastructure in place, meaning it is actually being
    hosted physically under your ownership in an IT center, then the line is the
    issue. Are you saying the consultant also owns that, or is he the SOA of
    your public domain name (meaning he is actually hosting the domain name on
    his own servers somewhere else and that went down), and your DNS servers are

    Reliability = control of your own resources. Move everything so you have
    control, including domain ownership.

    Hi Ace and Grant,

    Thank you for your both response.

    First, how do I know which has the SOA of the zone. If I get on my external
    dns, the soa record is my dns server itself. Or how do I determine who is the

    Also, the consultant does not host any Domain Name servers for us, and does
    not own our network infrastructure here. But sure he owns the domain name.

    The DNS server I have in our own server room is the primary (how do I
    recognize which server is primary or secondary?)

    In fact, this is not the first time...almost once a year since I worked here
    4 years ago. But this time is the longest downtime, and the worst. Their
    service is no good too! They never contact you for the down time, and what
    causing it.

    So may you guess why their internet down would really affect us? I really
    cannot explain this well to my supervisor.

    Finally, I may not want to mention their name know US always like
    "law sues" :)

    But no matter what, thank you very much for your responses!

  7. Oh, ok, so you are hosting your own public domain zone on your own DNS
    servers. I assume you have a minimum of two DNS servers to host your public
    zone and record (as per the Registrar's minimal requirements).

    I also assume these DNS servers are not the same ones being used for your
    internal Active Directory infrastructure.

    To find which DNS servers are SOA for your *public* zone, you can use
    nslookup. Run the following commands. The 'server' command makes it
    use an external DNS server to perform the query, and not your internal DNS,
    so you can get an accurate external result.
    (the results are displayed here)

    And then find your nameservers:
    (the results are displayed here)

    I believe you mentioned your public website is hosted elsewhere, such as a
    hosting company.

    What will happen if your line goes down, is when people on the internet try
    to get to it, they won't be able to resolve the IP address in order to
    connect. If the website is hosted externally at a hosting company, it will
    still be up and running, but no one can get to it because your public DNS
    servers are not accessible, therefore no one can resolve the name
    ( to the web server's IP address.

    If the webserver is hosted internally at your site, people won't be able to
    resolve the name to IP, nor get to it anyway because the line is down.

    Either way, I would request the consultant to make a registrant name change
    to be put into your city's name, with a contact name from the city. It
    belongs to the city.

    As far as the line, I believe you are saying your line is actually being
    rented/leased from your consultant's company? Whomever it is, if the line
    goes down with most DS (digital services) line providers, such as T1, T3 or
    even fiber digital (not cable, DSL or FIOS), they usually call a predefined
    contact number at your location to inform you and their plans on repairing
    it with a timeline when they believe it will be up again. If your line is a
    T1, T3, etc, this is normal procedure, however if its DSL, cable or FIOS, (I
    kind of doubt it's FIOS since FIOS is a recent implementation), they don;t
    do that. You would wind up calling saying the line is down, asking why, you
    need someone to fix it, and asking them how long it will take.
