watzatsong.com switched servers a week ago. both are hetzner servers. after switching the website files and database from old server to new server, we updated the ip address pointers inside the cloudflare dns records. but sometimes when we go to DNS Propagation Checker - Global DNS Testing Tool we see that propagation is still pending in some parts of the world. why and how is this happening? please help us. if this continues our SEO might be hit.
