As I’ve learnt this behavior seems to be normal and that the propagation will take a couple of hours or days of time… My Question is now, is there a … Read More “Is their a way to check if a Name Server change will be really propagated/get affective?” »

What causes multi-week propagation delays/partial propagation?

Posted on 08/21/2023 By firstdns

Generally, when transferring a domain’s nameservers, propagation happens at a predictable speed. However, it seems that some DNS hosts take a long time. For example, I have a client that is *sigh* transferring their domain to their web host. The new nameservers are loaded properly and are propagating a little bit, but only about 50% … Read More “What causes multi-week propagation delays/partial propagation?” »

How can I identify bad DNS hosting providers?

I’m not a DNS expert so Forgive me if I don’t have the right nomenclature. I suspect my all-in-one web host where our domain lives is somehow a bad DNS provider and somehow is slowing down our server response time / TTFB. This comes after umpteen performance optimizations and WPEngine demonstrating that our site runs … Read More “How can I identify bad DNS hosting providers?” »

I’m preparing to transfer a domain to another registrar, so I’ve disabled DNSSEC at the old registrar. But it’s been a few days and I’m still seeing DNSSEC records in the output of their nameservers (DNSKEY, RRSIG etc.) Will this have any bad effect if I transfer now or should I ask them to clear … Read More “Moving domain with leftover DNSSEC records” »
