Slow everything after applying openDNS to our router

    DNS does not change your speed (upload/download).  DNS is the phone book of the internet, not the phone lines.  The speed is solely determined by your ISP, the peering network carriers and the servers you are communicating with.

    "I thought open DNS was supposed to be faster."

    Yes, DNS is faster (the phone book) than your ISP's or others, not your speed rates.

    To analyze your problem, copy & paste the complete plain text output of the following diagnostic commands to here:

    nslookup -type=txt debug.opendns.com.
    nslookup whoami.akamai.net.
    tracert 208.67.222.222
    tracert 208.67.220.220

    Where exactly do I paste the information you supplied?

    You copy the plain text from your Command Prompt window on a computer where you executed the commands to paste it here into the forum.

    "I was able to follow all the instructions"

    Can you also post a link to the instructions you have followed, so that I can see what you did?

    Thanks for the information.  Honestly, I can see nothing which would indicate a problem with DNS or your connectivity to the OpenDNS DC in Dallas.  If you continue having troubles when using OpenDNS, I suggest to run the diagnostics as of https://support.opendns.com/hc/en-us/articles/227988487, and then raise a support ticket with a link to the diagnostic results and another link to this thread.

    I experience the same slowness.  I think the answer here is far too simplistic.    My subjective experience is the same:  Very slow internet after configuring OpenDNS.  I was using TrustPower here in NZ.  

    I am not a Networking Specialist - but I am an IT Architect.  I ran an DNS speed check here in NZ and was getting 150ms latency for many lookups.  If you browse a complext WebSite that pulls info from many sites, then all this latency adds up - which could add up to many seconds.    OK you have to consider DMNS caching too - so maybe I should have just waited a while until many of the addresses were cached.  But This is maybe the 3rd or 4th time i have tried OpenDNS.  I love the technology in theory - simply from easy of use - and the fact that it covers all devices in the house - but the factor that prevents me from using it is speed - maybe i don't understand the details - but subjectively - it does not work for us here in NZ.  Too slow.

    Well, do what I said two years ago: run the diagnostics and raise a support ticket.

    @redkea funny I should read this having the exact same provider in the same country.

    Funny how this was a dead thread. Great response from rotblitz. Thanks for the sensible chuckle.

    Anyways, searched this exact issue to see what others were saying about the subject at hand.

    I for one had started having issues but this wasn't an issue with openDNS, no it was an issue on my network. I won't go into great detail but some factors to consider when troubleshooting an issue like this is are questions like wired vs wireless devices, all devices vs a few or 1 or devices in certain areas or connection to certain switches or access points respectfully. Latency from said device to your gateway or gateways if multiple subnets are configured to segregate certain traffic from other traffic, like IOT from talking to LAN or WLAN networks in the same domain.

    I can go on and on but my issue simply put was a modem issue that was resolved with a quick config change and a reboot.

    This is not meant to be a post with a solution. Sorry for that but more a means to advise anyone to look in places that may not seem so obvious at first. Good luck to any wonderers coming through!

    I just added a raspberry pi running DNS ad-blocker "pi-hole" to our network ... and browser load speeds are TERRIBLE.   3-5 seconds and sometimes Chrome is timing out with unable-to-load page messages.  The second time we refresh the page, it's near-instant -- the pi-hole server has finished and cached the lookup.  So I configured pi-hole to use Cloudflare's DNS and the first-load of everything is back to near-instant.   I came here looking to see if there's a premium subscription that gives the faster DNS server ... but this is it.   However, these forum pages are also taking forever to load, even with Cloudflare DNS !!  Maybe there's an internal issue causing all opendns servers to go into a slowdown?    I hope so.  I will stay with opendns for its blocking of porn and scam sites (parent of kids).  Will check back later to see if the issue's resolved itself.  If OpenDNS has speed hiccups once a in a while .. we can live with that.
