The same old DNS issue, but for releases.mozilla.org this time

Plusnet's DNS servers don't seem to want to resolve "releases.mozilla.org" today:

Re: The same old DNS issue, but for releases.mozilla.org this time

I've found the same problem resolving to some work web apps. I've changed my dns servers to google as they are more reliable.

Re: The same old DNS issue, but for releases.mozilla.org this time

Apparently it's because the DNS servers listed for releases.geo.mozilla.com, ns0.geo.mozilla.com and ns1.geo.mozilla.com, don't seem to be working.
See: https://groups.google.com/forum/?fromgroups=#!topic/mozilla.support.firefox/g9j1FbvX9fY
dig @8.8.4.4 releases.geo.mozilla.com ANY

On a DNS related note, I also discovered that the DNS server in my router (DG834Gv3) won't respond to dig unless I add "+noadflag" on the end.

On a DNS related note, I also discovered that the DNS server in my router (DG834Gv3) won't respond to dig unless I add "+noadflag" on the end.

I'm using 29-01-08_dg834v3_dg834gv3_4_01_37 i'll plug something in and try it for a laff, i use it for an AP so no big deal apart from i have a Cups Print server running on a Raspberry.
Glad you found the answer to the DNS issue  Smiley
