Amazon has changed the domain that they use to serve Fire TV software updates

Amazon has switched from using the domain to now using the domain for serving software update files to Fire TV devices. This is only important to know if you are someone who is currently blocking Fire TV software updates by denying access to Amazon’s file hosting domain. If you have router or DNS filters set, you should update them to include the domain It is unknown if the sub-domain d1s31zyz7dcc2d is fixed or if it will change with each release, but all software update files arrived on my Fire TVs and Fire TV Sticks from that same exact sub-domain.


10/30/18 Software update is being served by the same exact subdomain (d1s31zyz7dcc2d) so, for the time being, it appears as though it will not change from update to update.

    Thanks for the quick info Elias!
    I set rules on my router a couple years back so a 10 second edit was all it took. Though I’m kind of at the point where I don’t really care that much anymore.
    Any way of knowing if this is a “trickle out’ update or a quick burst to most machines?
    I bought my 2 Gen 1’s within a week of initial release and as I recall they use to receive updates pretty quickly.

    It seems that the URL is just how Cloudfront generates URLs by default and I guess Amazon thought it was pointless to use CNAMES:

    So hopefully this means that this will be static, at least for the time being. Would seem weird to regularly change URLs since that would just break the update system, unless they use another site for getting the URLs, kind of like a pointer.

    If I did not get update what should I do if anything.

    When will the spectrum app be offered on Fire stick.?

  5. Frank Nitty says:

    Having to block Amazon’s OTA updates all the time would seem like a chore just to avoid whatever new features they decide to implement

    I am not a techie and this may not be the place to ask this, but why is it that I cannot watch a movie or back-to-back TV shows on my AFS without a “No internet connection” message/interruption? I don’t lose my internet connection on my tablet when this happens.

  7. Peter A. says:

    Does this affect the URLs used for Fire tablets as well?

  8. Scott says:

    Ive always received updates very late. Usually a week or even later after a release. The last update I received within a day of you announcing it. Not sure if this is the cause but definitely different.

    I meant Vudu sorry I want the spectrum app too

    If you run a VPN, this method will not work.
