I have had hundreds of domains over the years, and generally, the 24 to 48 hour rule applies. Sometimes even much quicker. I've learned that the registrar you use affects it a lot. GoDaddy usually takes minutes, whereas hostgator generally takes 24 to 48 hours; however, now I am using 1&1 IONOS. It has been 4 days since I updated the Name Servers and they still haven't propagated. My host is GoDaddy. So I am pointing my Name Servers to GoDaddy. I have tried http://dns.squish.net as recommended on another (older) StackExchange question. And that didn't give literally ANY information, except that it "failed".
Can someone possibly identify the problem for me as I really need to get this website up and running? I would appreciate it. http://insidethereport.com
Also, GoDaddy nor IONOS customer service knows what they're doing. I have called GoDaddy, they said call IONOS. IONOS said, call GoDaddy. It's like a never ending while loop lol
