title: www-record in DNS keeps pointing to GitHib even after CNAME-records were deleted
body: <p>I had some static websites (<a href="http://www.lithouse.eu" rel="nofollow noreferrer">www.lithouse.eu</a>, .nl, .lt, .fr, .it) hosted on GitHub. Two days ago I moved the site to a co-located server in Germany. The websites now run on Ubuntu server 20.04, apache and ISPConfig 3.2, I updated the DNS-records (the .eu and .fr records are at EuropeRegistry, .nl and .it are at GoDaddy, .lt is with hostex in Lithuania). I actually have only one website (.nl) and the Ubuntu server does a 301-redirect for the other domains.</p>
  <p>All looks ok, except for <a href="http://www.lithouse.eu" rel="nofollow noreferrer">www.lithouse.eu</a>, and then only the www, not the TLD. Look at the output of my host-command:</p>
  <pre><code>$ host lithouse.nl
  lithouse.nl has address 65.21.239.8
  $ host www.lithouse.nl
  www.lithouse.nl has address 65.21.239.8
  $ host lithouse.eu
  lithouse.eu has address 65.21.239.8 (so far all looks ok)
  $ host www.lithouse.eu
  www.lithouse.eu is an alias for invalid_now.yga01.github.io.
  invalid_now.yga01.github.io has address 185.199.109.153
  invalid_now.yga01.github.io has address 185.199.108.153
  invalid_now.yga01.github.io has address 185.199.110.153
  invalid_now.yga01.github.io has address 185.199.111.153
  invalid_now.yga01.github.io has IPv6 address 2606:50c0:8000::153
  invalid_now.yga01.github.io has IPv6 address 2606:50c0:8003::153
  invalid_now.yga01.github.io has IPv6 address 2606:50c0:8002::153
  invalid_now.yga01.github.io has IPv6 address 2606:50c0:8001::153

  <p>The last one, <a href="http://www.lithouse.eu" rel="nofollow noreferrer">www.lithouse.eu</a>, goes wrong. I used to have a CNAME-record on github and in the DNS that pointed to lithouse.eu. Initially I changed the CNAME in the DNS to point to invalid_now.yga01.... so as to make it useless, and then one hour later I deleted the CNAME record altogether, both in the DNS and on github. Actually, my entire github repository is empty now, I have nothing left there, no projects, nothing.</p>
  <p>The DNS of lithouse.eu is on Europe Registry, looks as follows:</p>
  <pre><code>1 @ SOA ns1.instradns.com. root.instra.com. 2011012602 28800 7200 604800 86400

  <p>Both lithouse.eu TLD and the www-record point to 65.21.239.8, yet somehow the host-command returns some github-stuff that I don't want. Strangely, when I check the DNS at <a href="https://dnschecker.org/" rel="nofollow noreferrer">https://dnschecker.org/</a> I see that the whole world is looking at the correct IP's, also for <a href="http://www.lithouse.eu" rel="nofollow noreferrer">www.lithouse.eu</a>. Except me, I get to see some github-stuff and when I enter <a href="http://www.lithouse.eu" rel="nofollow noreferrer">www.lithouse.eu</a> in my browser I indeed arrive at a 404-page at github.</p>
  <p>I cleaned all caches, rebooted routers, rebooted a linux-PC and a mac, but clearly I must be missing something very basic. Final remark: I did the DNS-changes 24 hours ago. Should I wait even longer? Then why do some changes propagate properly, but not this CNAME-thing?</p>
  <p>Anyone any suggestion?</p>
