I’ve just changed our nameservers (this is who manages our domain and all connections to it) from CloudFlare to Google. Any DNS change, such as this one, can take time to fully prorogate through the internet. Some users may see the website or Minecraft server as offline for short period. It is not actually offline! If you see if offline you can try clearing your cache, and even try changing your DNS servers to Google’s (22.214.171.124 and 126.96.36.199), but you may just have to wait it out. It will fix itself.
