OpenDNS Issue (Gmail.com)

So if anyone has been having issues emailing to gmail users lately I finally found out why.
OpenDNS apparently is having kittens doing proper resolves for any of it.

Now if you’re an OpenDNS user you might say my settings were wrong or something.
Well I reviewed all my settings (disabled all security stuff and filtering) and I would get a bunch of NXDOMAIN(3) errors.

host gmail.com:
gmail.com has address 74.125.228.53
gmail.com has address 74.125.228.54
Host gmail.com not found: 3(NXDOMAIN)

Whereas using he.net’s dns:
host gmail.com:
gmail.com has address 74.125.225.117
gmail.com has address 74.125.225.118
gmail.com has IPv6 address 2607:f8b0:4009:802::1016
gmail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 5 gmail-smtp-in.l.google.com.

Quite a big difference eh?

So for the time being we will stop using OpenDNS as our primary dns provider until the issue is resolved.

Network Issue (He.net) Resolved

Hurricane Electric is back up and working and so is our DNS.

Our primary DNS provider for inexistence.org (Hurricane Electric) is having kittens,

DNS.he.net is experiencing an issue at the moment. For those that are missing zones, we are in the process of recovering them at this time.

This also includes tunnelbroker.net which is how our IPv6 works so yeah epic fail on their end.

As of right now all *.inexistence.org services will probably not work for you.
If you know how to edit your hosts file you can temporarily fix it by referring directly
to our IP: 216.196.207.102.

216.196.207.102 inexistence.org
216.196.207.102 mail.inexistence.org
216.196.207.102 www.inexistence.org
216.196.207.102 cubemail.inexistence.org

If their servers continue to be down for too much longer I might change DNS servers.
I am willing to give them a chance to fix it as their services rocks with it’s working…
All other hostnames will continue to work (we use cloudflare for everything else).

IPv6 Certification

I’m currently doing all the he.net (Hurricane Electric) IPv6 certification tests.
I had to change inexistence’s main dns stuff around for a test on the site.

All other domains are still going through cloudflare
so you shouldn’t see any outages with your domains.

Though inexistence.org might go down for a few till I complete the testing.
This will affect mail and other services possibly.

If this occurs you should be able to access all services by substituting your own
domain in place of inexistence.org aka mail.inexistence.org becomes mail.mydomain.com.

You will see ssl cert warnings if you do this.
Believe me if downtime occurs I’ll be fixing it quickly.

No downtime yipee! Apparently I still have my DNS skills.

Thanks for the understanding!
