I'm using Dyn host for a long time and working well until yesterday morning (GMT+7) I can't access to Dyn host I checked IP Address it's show on website and update correctly but i try to nslookup using google public DNS 8.8.8.8 and Cloud flare 1.1.1.1 it show the wrong IP and wait for a long time it didn't update to correct one as shown on dyn website. I think something wrong with DNS server in dyn system please check..
