Hi, I have reports from people using Spectrum Internet US that they can’t access our site after migration to a different service. I now know that they can update to google’s DNS 184.108.40.206. and then everything works again but for some reason spectrum’s own DNS is not updated with the correct new server IP. My site is running through cloudflare.
I feel I can’t really ask customers to fiddle around in their DNS system, that’s way too technical so what is the best way to solve this? Spectrum internet is not really reachable if you don’t have an account with them and they do not respond to messages on e.g. social media
