services: please allow several hours for DNS records to update
me when I've changed the records and it's not working after 5 minutes: i am a failure at computers
These can help:
https://1.1.1.1/purge-cache/
https://developers.google.com/speed/public-dns/cache…
My usual mistake is setting most of the records I need to change to 1m TTL first but forgetting one. Then spending 1 hour trying over and over again hoping it's finally going to work.
